Prinsenhof (Courtyard of the prince) is a complex that has been transformed and expanded over time. It was founded around 1400 as the St. Agatha monastery for women. In the sixteenth century the prestige of monasteries declined in Delft and in 1572 the Netherlands reformed and Catholicism was forbidden. A part of the monastery was transformed into housing for prince Willem van Oranje, an ancestor of current king Willem-Alexander. He is considered as one of the founders of the Netherlands as we know it today. On July 10 1584 Prinsenhof was the location of his murder by Balthasar Gerards. He was shot at the bottom of the staircase, which is now known as the murder staircase.

Nowadays you can visit the building as a museum. It is accessible through three gates that each have their own relief that commemorate the different functions of time. On the side of a complex you can see a garden and access the courtyard.
