In medieval Dutch the words Burg, Burcht (Burh or Burgh) referred to a fortification which would serve as a refuge in times of danger.

The word Huis (house), later Kasteel (castle) referred to the defendable home of a nobleman.

Before the construction of stone fortifications began, the medieval Netherlands had a number of burgs comparable to Viking ring fortressess.

[3] Shortly before 1100 this castle consisted of a 9 m high motte with a wooden defensive building on top.

[2] Meanwhile, the most important noblemen of Holland and Zeeland also began to build mottes, notably Egmond Castle and Borssele.

At the end of the 13th century, a ringwall was constructed around the main tower, about halfway from the top of the motte.

The outer bailey has not been subjected to an archaeological excavation, but this configuration is known from maintenance accounts dating from the 14th to 16th centuries.

[5] A picture of the buildings at Oostvoorne made by Cornelis van Alkemade in about 1700, shows the outer bailey, not only in front, but entirely encircling the motte.

If this picture is correct, one can speculate that the Burcht of Voorne was built inside an earlier Viking ring fortress type of earthen fortification.

The protected walkway had an average width of 3 m.[6] The Burcht of Oostvoorne was owned by the Lords of Voorne.

During the Loon War (1203-1206) Hugo van Voorne supported Ada, Countess of Holland.

[11] Adriaan Kluit visited the site for his unpublished work 'De Landen van Oost-, West- en Zuid-Voorn'.

The ruins of the Burcht of Voorne remained the property of the state till 15 January 2016.
