Later it was the main city in this region, that was formerly called Land van Vollenhove. Vollenhove was the summer residence of the bishop of Utrecht, the ruler of these parts. He lived in the castle Toutenburg, of which only some small ruins are left now. To be near their lord, quite some nobility moved to Vollenhove. They built their estates (Dutch: havezates) in the town, which was unique. Therefore, Vollenhove was called the city of palaces. Like Blokzijl, peat transport to Holland by ship caused the small city to flourish during the 17th century.
