(Nieuwstraat 23) came from the Logement of the Committed Boards of West Friesland and the Noorderkwartier.
The sisters of the St. Cecilia Monastery established themselves in 1402 on the Nieuwsteeg. Of the chapel built by them in 1435, which was enlarged shortly after 1472 and provided with a nun gallery, the roof construction with draw beams and key pieces still remains. This hood does have the ribs but not the wooden shell of a barrel vault. The chapel and the adjacent paterhuis (circa 1500) arrived in 1577. For the Committed Boards, a slightly kinked cross-section was erected in 1613 on the Nieuwstraat with two rich maniaristic stepped gables, provided with claws and between them a middle element with the arms of Holland, West Friesland and the United Netherlands. The sandstone Doric entrance gate may have been hewn by Berent Gerritsz van Kampen (vases of the 18th century). On both gables there is a statue of Prince Maurits. In 1618 a corridor was built along the Nieuwsteeg as a connection with the chapel and around 1630 a beam layer was placed in the choir part of the chapel for the large hall for the Committed Boards. During a renovation in 1754-'56 the closing of the chapel was demolished. In 1787 Leendert Viervant was commissioned to decorate the large hall in a sleek Louis XVI style.
After the abolition of the Committed Councils (1795), the building was taken into use in 1797 as a town hall and the great hall as a shed. The front section served as a district court from 1850 to 1877 and the space beneath the nun gallery from 1857 to 1921 as a police station. The current frames date from a restoration in 1904. Further restorations were carried out in 1970 and in 1997 (J. Büchner). In 1977 a new town hall in the Risdam (A.E. Küpfer of architectural firm P.H. Tauber) came into use.
