Gijsbert Dommer Huis

Historic Building in Southern Canal Ring

This handsome greystone house is known dramatically as the 'House with the Blood Stains'. Six-time mayor and diplomat Coenraad van Beuningen lost his fortune, then his mind, and scribbled graffiti on the facade, allegedly in his own blood. His mysterious 17th-century writing – which includes Hebrew letters and obscure Kabbalah symbols – is still faintly visible.

Wealthy businessman Gijsbert Dommer commissioned the house in 1671, hence the name.
