Athens Museums Opening Hours

Athens museums opening hours: the summer and winter split, the closed days and the late nights

Athens museums opening hours change twice a year, and that single fact causes more wasted journeys than anything else in the city. The Acropolis closes at 20:00 in July and at 17:00 in January. The National Archaeological Museum runs until 20:00 every day in summer and shuts at 15:30 on most winter afternoons. The Temple of Olympian Zeus drops from a 20:00 close to a 15:00 close, with last entry at 14:40. A visitor who looked up the hours in August and turns up in November at 16:00 finds a locked gate. The table on this page puts the summer timetable and the winter timetable side by side for every museum and site we hold verified hours for, with the weekly closed day next to them.

The second source of trouble is that the state museums and the private museums run on different rhythms. State sites are open seven days a week with early winter closes and a holiday list that shuts everything at once. The private museums keep one timetable all year, close on a Tuesday, and stay open late on one evening. Both are easy to plan around once you know which kind of museum you are looking at. These are the Athens museums opening hours as we last checked them on the museums' own sites on 10 and 11 September 2026. Timetables do shift, and the museum's own site is the final word on the day you travel.

Summer hours, winter hours, and the dates that switch them

The Ministry of Culture sites follow a summer timetable and a winter timetable, but not every museum switches on the same day, and that is where the traps start. The Acropolis Museum, the War Museum, the Herakleidon and Delphi all run summer hours from 1 April to 31 October and winter hours from 1 November to 31 March. The Ancient Agora treats April to August as full summer and then steps its closing time down every fortnight through September and October. The Acropolis and the Temple of Olympian Zeus do the same: 19:30 for the first half of September, 19:00 for the second half, 18:30 for the first half of October and 18:00 for the second, with last entry always 30 minutes before the close. The National Archaeological Museum is later than everyone: its 2026 summer timetable runs from 4 May to 15 November, so in late April it is still on winter hours while the Acropolis has already stretched to 20:00.

A few museums do not switch at all. The Byzantine and Christian Museum and the Numismatic Museum keep 08:30-15:30 in every month, which makes them winter-style museums even in July. The Museum of Cycladic Art, the Benaki, the Goulandris Foundation, the National Gallery, the Ilias Lalaounis Jewelry Museum and the Museum of Illusions publish one timetable for the whole year. The Hellenic Motor Museum publishes no summer or winter split either. And the National Historical Museum runs its own version of a seasonal split: from September to June it opens at 09:00 on weekdays, and in July and August it opens an hour later, at 10:00, every day it is open.

Athens museums opening hours by season: the table

Times are the published opening and closing times. Where a museum runs a single timetable all year, the same hours appear in both columns. "Closed" is the weekly closed day only. Public holidays are covered further down. Last-entry times, where they matter, are in the sections that follow.

Two rows deserve a second look. The National Archaeological Museum's Tuesday is not a closed day but a half day: it opens at 13:00 in both seasons and then runs to 20:00, which makes a summer Tuesday afternoon there one of the longer museum slots in the city. And the Museum of Modern Greek Culture in Monastiraki is a state museum that keeps one timetable all year, with three long days (Wednesday, Saturday and Sunday to 20:00) and three short ones, so check the weekday before you go rather than the season.

Last admission: the 20 to 30 minute rule

Closing time is not the time you can still walk in. Almost every museum in the table stops selling tickets or admitting visitors 20 to 30 minutes before the published close, and the archaeological sites are strict about it. The Acropolis, the Acropolis Museum, the Ancient Agora in summer, the Temple of Olympian Zeus in summer, the National Archaeological Museum, the Hellenic Motor Museum, the Herakleidon, the National Historical Museum and the War Museum all work on 30 minutes. The Numismatic Museum, the Ancient Agora in winter, the Temple of Olympian Zeus in winter and Delphi work on 20 minutes, and the National Archaeological Museum and the Byzantine and Christian Museum clear their galleries 20 minutes before the doors shut regardless of when you came in. The Goulandris sells its last ticket 30 minutes before closing and admits its last visitor 20 minutes before. The Museum of Cycladic Art is the most forgiving, at 15 minutes.

Three museums cut off a full hour early, and they are the ones people miss. The Benaki's last entry is one hour before closing, so a Sunday visit has to start by 15:00. The National Gallery is the same, which means 21:00 on its late Wednesday. The Museum of Illusions closes at 20:00 but takes its last entrance at 19:00. If your plan puts one of these three at the end of the day, work backwards from the last-entry time, not the closing time, and give yourself the length of a proper visit on top.

Monday, Tuesday and Sunday: who closes when

Athens has no single closed day, which is helpful, but it does have a pattern. Tuesday is the closed day at seven museums in the table: the Benaki, the Byzantine and Christian Museum, the Goulandris Foundation, the Museum of Cycladic Art, the Numismatic Museum, the National Gallery and the Museum of Modern Greek Culture. The Herakleidon joins them from November to March, when it also closes on Monday. So a Tuesday in Athens is a day for the big archaeological sites and the National Archaeological Museum after 13:00, not for the Kolonaki and Vasilissis Sofias museums.

Monday is the closed day at only one museum we track, the National Historical Museum in the Old Parliament building on Stadiou Street, plus the Herakleidon in winter. Monday is also a short day at the Acropolis Museum, which closes at 17:00 on Mondays in both seasons while it runs to 20:00 or 22:00 on every other day. Sunday is the odd one out: the Ilias Lalaounis Jewelry Museum near the Acropolis is closed on Sundays, the Benaki shortens to 10:00-16:00, the Cycladic opens an hour late at 11:00, and the Hellenic Motor Museum opens at 11:00 at the weekend instead of 10:00. The state sites, by contrast, treat Sunday like any other day, and in winter the first Sunday of the month is a free day at most of them, which our free museum days in Athens page covers in detail.

Public holidays: state sites close, private museums close longer

Six dates close nearly every state site in the city: 1 January, 25 March, 1 May, Orthodox Easter Sunday, 25 December and 26 December. The Acropolis, the Ancient Agora, the Temple of Olympian Zeus, the National Archaeological Museum, the Byzantine and Christian Museum, the Numismatic Museum, the Museum of Modern Greek Culture and Delphi all list them. The Acropolis Museum is the one exception on 25 March, when it opens and is free. Around Easter, the sites do not close outright but shorten: the Acropolis, the Ancient Agora, the Temple of Olympian Zeus, the Byzantine and Christian Museum and Delphi open 12:00-17:00 on Good Friday, and the Acropolis, the Agora and the Olympieion run 08:30-15:30 on Holy Saturday. The War Museum publishes its own short days: Good Friday 12:00-18:00, and Holy Saturday, 24 December and 31 December 09:00-15:00. The National Gallery opens 13:00-17:00 on Good Friday only.

The private museums, and the National Gallery with them, keep a longer holiday list. The Benaki, the Goulandris, the Museum of Cycladic Art and the National Gallery all add 6 January, Clean Monday, Easter Monday, Whit Monday, 15 August and 28 October to the six dates above. The Hellenic Motor Museum closes on 1 and 6 January, Easter Sunday and Monday, 1 May, 15 August and 25 December. The National Historical Museum closes on 25 and 26 December, 1 and 6 January, Easter Sunday, 1 May and 15 August. The Herakleidon lists 1 January, Orthodox Easter, 15 August and 25 and 26 December. The Lalaounis says only that it closes on national holidays and publishes no dates. The one museum that stays open through nearly all of it is the Museum of Illusions, which opens on every Greek public holiday except Orthodox Easter Sunday. Two dates trip visitors most often: 28 October, when the Acropolis is open and free but the Benaki, the Goulandris and the National Gallery are shut, and 15 August, when the archaeological sites are open and most of the private museums are not.

Late openings: the underused slots

Every long day in the Athens museums opening hours table is a chance to see a museum after the coach groups have gone, and most visitors never use them. The Acropolis Museum stays open until 22:00 every Friday, in winter as well as summer, which is the latest a state museum runs in Athens and the easiest late evening to plan, because the museum sits next to Akropoli metro station. The Benaki runs until midnight on Thursdays and opens its permanent exhibition free from 18:00, so a Thursday evening there costs nothing and follows a full day elsewhere without any rush. The National Gallery is open until 22:00 on Wednesdays. The War Museum, a few doors along Vasilissis Sofias from the Byzantine and Christian Museum, runs to 22:00 every Saturday.

The shorter late slots are just as useful for a second museum in the day. The Museum of Cycladic Art runs to 20:00 on Thursdays, the Goulandris to 20:00 on Fridays, the Museum of Modern Greek Culture to 20:00 on Wednesdays, Saturdays and Sundays, and the Museum of Illusions to 20:00 every day. In summer the National Archaeological Museum is open until 20:00 every day of the week, and the last two hours are the quiet ones. Put together, that means a winter week in Athens has a late museum on Wednesday, Thursday, Friday and Saturday, and none of them involves an archaeological site closing at 17:00.

How to plan a day around the hours

The pattern behind the Athens museums opening hours table is simple once you see it: the archaeological sites and the big state museum open early and, in winter, close early. The private museums open at 10:00 and one of them stays open late each evening. So the day that works is sites first, museums second. In summer, be at the Acropolis gate at 08:00, take the Ancient Agora or the Temple of Olympian Zeus in the late morning, and leave the Acropolis Museum or a Kolonaki museum for the afternoon, when the sun is hardest and the galleries are air-conditioned. In winter the same order matters more: the Acropolis closes at 17:00 with last entry at 16:30, the Agora at 16:30, the Olympieion at 15:00, and the National Archaeological Museum at 15:30 on six days out of seven. A winter afternoon in Athens is museum time, not site time, and after 18:00 only the late openings above are left.

Check the weekday before you check the season. A Tuesday costs you seven museums. A Monday costs you the National Historical Museum and gives you a short Acropolis Museum day. A Sunday costs you the Lalaounis. Then check the holiday list for your dates, because the Ministry closures are total and there is no timed ticket that opens a closed gate. Finally, treat this page as a snapshot: these are the hours as we last checked them, the state museums in particular have moved their seasonal switch dates before, and the museum's own site on the morning of your visit is the only version that counts.

1. Match the season to the site, not to the calendar. Summer hours start on 1 April at most state sites but on 4 May at the National Archaeological Museum, and the closing time steps down every fortnight through September and October at the Acropolis, the Agora and the Olympieion. Read the row for the exact site, then the exact fortnight.
2. Start with the site that closes earliest. In winter that is the Temple of Olympian Zeus at 15:00, then the Byzantine and Christian Museum and the Numismatic Museum at 15:30, then the Agora at 16:30, then the Acropolis at 17:00. Book an early Acropolis ticket slot and let the museums fill the afternoon.
3. Work back from last entry, not closing time. Thirty minutes at the sites, an hour at the Benaki, the National Gallery and the Museum of Illusions. Add the length of the visit you actually want, and that is your arrival time.
4. Use one late night for the museum you would otherwise rush. Friday at the Acropolis Museum until 22:00, Thursday at the Benaki until midnight, Wednesday at the National Gallery until 22:00. A booking with free cancellation for the paid sites keeps the rest of the day flexible if a timetable turns out to have changed.

Where to go next

Athens museums opening hours are half the plan. The tickets are the other half. Our Acropolis Museum tickets page covers the timed tickets, the Friday late night and the guided options from about €35, and the National Archaeological Museum tickets page explains the Tuesday half day alongside its tickets and guided tours. If you are counting three or more paid sites across the same days, price the Athens City Pass against single tickets before you book. For a day that starts before the museums open, the Athens hop-on hop-off bus runs from 08:30 at Syntagma, and the Delphi day trip follows the same summer and winter site hours as the Athens sites, so a winter departure is a morning-only visit there too.
