Het Calmershuis
This stately building has seen its fair share of turbulent times. It was built around 1250, making it one of the oldest stone houses in the city.

By the standards of the time, this was a colossal structure. Its construction therefore took many years. The building owes its name, Calmershuis, to its owners in 1338: the Calmer family, who were mayors. In 1920, the house was sold to the Wolters publishing house, after which it became part of the Wolters-Noordhoff complex. A few years after the publishing house moved out, het Calmershuis became a squatters’ stronghold. In 1990, the building was at the centre of squatter riots, following which it was cleared. Today, the building houses the Open University.
