Montaigne’s library was located in this circular tower at the Château de Montaigne, near Bergerac and Saint-Emilion. You can take a virtual tour of a reconstruction of the library — in the sense of a room — at the Musée d’Aquitaine’s website. Click on it and you can drag the cursor around to rotate the display.

Moving from the sense of library as a room, to its meaning as a collection of books, Cambridge University Library’s Montaigne’s library contains Gilbert de Botton’s attempt at assembling all the books in Montaigne had in that room. Their collection includes ten copies which were actually owned by Montaigne, and links take you to digitized versions of a few of them.
