The site museum is housed in the Ottoman-era tower that stands just inside the main gate, at the top of the path from the ticket office. The collection is modest but well-chosen: a selection of inscriptions, sculpture fragments, and small finds from the excavations, displayed with English-language interpretation that sets them in the context of the site's successive occupations.
The star exhibits are the Roman portrait heads and a series of inscriptions recording the names of freedmen — formerly enslaved people — who won their liberty at Butrint, a practice documented at the site in unusually large numbers. The tower itself is worth ascending for the view over the peninsula, the lake, and the Straits of Corfu.
