Dating from 1672 and set in a beautiful canal house, the Museum Van Loon (museumvanloon.nl; adult/child €16/9) was first home to acclaimed painter Ferdinand Bol. By the late 1800s, the Van Loons, a prominent patrician family, had moved in and have lived here ever since; they still occupy the building's upper floors. It's filled with opulent furniture and family portraits, but the main exhibit is the house itself. It's full of set-piece interior decoration, with intricate wedding-cake stucco on the ceilings. Temporary art exhibitions and concerts take place throughout the rooms.
Downstairs is the old-fashioned basement kitchen. Original blueprints were used to restore the wine cellar, pantry and storage room.
This is the only such mansion where you can still see a rear coach house, which once housed up to eight horse-drawn carriages. It's outside, at the end of the pristine formal courtyard garden. Its small cafe is a lovely place for a coffee and appelschnitt (apple strudel).
