Oudezijds Voorburgwal 231, 1012 Amsterdam - Binnenstad - Oude Zijde, ,
The Agnietenkapel (the Chapel of Holy Agnes) is the only medieval chapel in good condition in Amsterdam.
It was built in 1397 and rebuilt after a fire in 1470. From the foundation of the Athenaeum Illustre - precursor of the University of Amsterdam - by Vossius and Barlaeus in 1632 the Agnietenkapel was the center of scientific activities.
It is now the University's history museum.
