"Hof te Dieren" was the house of the Dutch Stadtholder Frederik Hendrik of Orange, William II, Prince of Orange, William III of Orange and William IV of Orange. They enlarged the house and held hunting parties in the nearby woods. A road was built, connecting Dieren to The Hague, which is called the "Koningsweg". The road can still be found in many places in the Netherlands, such as Otterlo.

They were actually located in "Avegoor", a building located to the south-west of Dieren.
