In the guestbook it is written that Albert Einstein visited the Spinozahuisje on November 2, 1920.
Benedictus de Spinoza was the most famous philosopher of rationalism in the Netherlands in the 16th century.
He lived in this house from 1661 to 1663 and in 1899 they turned it into a museum.
The museum rooms have a unique collection of books from his former library that are unique in the world.
