Lange Jaap

Since September 2021, an area with a radius of 70 meters around the lighthouse has been fenced off due to concerns that the tower may topple over.

The first aid to navigation at the site was a simple coal-fire light from 1814, at Fort Kijkduin, a few hundred meters north of the current tower.

The light consisted of 26 Argand lamps with parabolic reflectors, visible at a distance of up to 6 nautical miles (11 km; 6.9 mi).

The cupola and lantern pane were replaced in 1992; the old shell is displayed outdoors in the royal dockyard of Willemsoord in Den Helder.

Due to the possibility of the construction collapsing, a 70-meter range around the lighthouse was completely blocked off.

The 17-storey 264-step tower was designed by Quirinus Harder and prefabricated by Penn & Bauduin in Dordrecht.
