The double-sized canal house of the Van Loon family dates from dates from 1672. The first resident was the painter Ferdinand Bol, a pupil of Rembrandt. The Van Loon family dynasty began with Willem, a founder of the Dutch East India Company, The Van Loon family, whose crest includes two Moors to represent the trade connection with the East, came to live in the house in the late 19th century. Thora van Loon-Egidius (1865-1945), was a Lady in Waiting, a Dame du Palais, of Queen Wilhelmina for 40 years, when royal guests were entertained here, and the house is much as she left it. The family still occupies the servants’ quarters on the upper two floors, and there are changing exhibitions.
