Beauclair Palace rises above Beauclair and is the seat of the dukes and duchesses of Toussaint, home to Duchess Anna Henrietta in Blood and Wine. It was built by elves and later restored by the architect Peter Faramond.

The palace is famous for its stained glass, marble floors and fine stonework, and it holds the largest library in the known world outside the universities, as well as a great Knight Hall. Few know that part of it is hidden by a powerful illusion, a secret passed down among the sorcerers of the ducal family. Geralt visits the palace many times over the course of the main story.
