The corner house, Grote Oost 132, has both fleets and booming cannon in
its frieze. The frieze on Grote Oost has the coat of arms of Prince Maurice.

This house and its neighbours, Slapershaven 1 & 2, belong to Vereniging
Hendrick de Keyser. Their restoration is dealt with in great detail with plans
photographs and [Dutch] commentary in Huizen in Nederland: Friesland en
Noord-Holland [Waanders Uitgevers Zwolle].
