Hadrian's Library is the grand marble complex that the Roman emperor Hadrian raised in the centre of Athens around 132 AD, the largest single structure he built in the city he loved. Far more than a library in the modern sense, it was a vast rectangular enclosure — roughly 122 by 82 metres — built as a cultural and intellectual centre for the city: a colonnaded courtyard for study and conversation, halls for lectures and readings, and, at its eastern end, the library proper, where papyrus and parchment scrolls were kept in tiers of niches set into the walls. It stands in the Monastiraki and Plaka district, just north of the Roman Agora and beside the Ancient Greek Agora, at the very heart of old Athens.
The enclosure was entered from the west through a monumental gateway, and it is a stretch of that west façade — a line of tall Corinthian columns standing before the marble wall — that survives as the landmark you see today from the square below. Inside, a peristyle of around a hundred columns of coloured marble ringed a great open courtyard with a long ornamental pool and garden at its centre, a serene space set apart from the noise of the city. Over the following centuries the complex was damaged, rebuilt and reused, and in Byzantine times several churches rose within its walls — among them the early Christian Tetraconch and, later, the church of the Megali Panagia — so that the ruins layer Roman grandeur with the Christian city that grew up inside it.
Hadrian's Library sits at the crossroads of ancient Athens, a two-minute walk from the Monastiraki metro station and within easy reach of the Acropolis, the Roman Agora and the Ancient Greek Agora, all of which lie close by. It is easily confused with its neighbours — the Roman Agora and the Greek Agora are separate sites with their own tickets — but the Library is a distinct enclosure of its own, and this ticket is entry to it alone. Because entry is now timed by the hour, we handle the ticketing in your own language and reserve the slot you want, so you can give your energy to the ruins instead of the queue.
