The lighthouse Huisduinen , called Lange Jaap , is a lighthouse in the north of Fort Kijkduin near Den Helder in the Dutch province of North Holland .
Building
With a height of 63.45 meters, the Lange Jaap was the highest lighthouse in the Netherlands for a long time before it was replaced by the new lighthouse on the Maasvlakte . The Lange Jaap is still the tallest cast iron lighthouse in Europe . The construction of the tower began in 1877, the commissioning took place on April 1st, 1878. The lighthouse has a sixteen-sided basic shape and consists of cast iron plates screwed together with a total weight of 506,100 kilograms. The architect of the tower was Quirinus Harder . The "Lange Jaap" has been a listed building since 1988 .
history
Before the Lange Jaap was built, shipping off the coast around Den Helder and Texel was secured by various lighthouses and beacons . There was also a tower on the site of today's Fort Kijkduin , on which wood and coal were burned to warn ships of dangers. In 1822, a 46 meter high stone tower was built on the fort area, on which a beacon equipped with 26 oil lamps and mirrors was installed. In 1853 the mirrors were replaced by a lens system before the old tower became superfluous with the construction of the Lange Jaap in 1878 .
beacon
When it opened in 1878, the Lange Jaap was equipped with an Argand lamp and stationary lenses. These were replaced by rotating optics in 1903. This lens system produced two flashes of light every ten seconds and could be seen about 30 kilometers away. In 1912 the lighthouse received even more powerful burners before it was electrified in 1924. During the Second World War , the beacon was destroyed by German marines. It was not until 1945, after five years without a beacon, that makeshift optics were installed, which were replaced by a new lens system in 1949. This system still generates four flashes of light in a twenty-second interval and can be seen 54 kilometers away.
