The first Slotkapel (Castle Chapel) - dedicated to Saint Catherine, the patron of the nobility, was built in 1229, commissioned by Willem I van Egmont. It was located next to the castle of Egmond. In 1430 Count Jan van Egmond ordered the demolition and rebuilding of the chapel in its current simple Gothic style as a one-aisled church.

The chapel and castle were destroyed in 1573 in the Eighty Years War, during the siege of the city of Alkmaar. In 1633 the chapel was restored by the States of Holland and West Frisia. Various cities, aristocrats and companies from that time made donations for the restoration, including the fantastic stained-glass windows. The unique clock in the centuries-old tower was made in 1682 by Christiaan Huygens.

In 1960 the Slotkapel was in a very poor condition and the municipality intended the demolition of the church. Due to the efforts of a group of citizens the chapel was restored and does still exist. Nowadays it serves as a venue for weddings, exhibitions and concerts.
