Nakkehoved Lighthouse  Nakkehoved Lighthouse (Danish: "Nakkehoved Fyr)" was originally the name for two individual lighthouses above the "Nakkehoved" cliffs"." Since the eastern lighthouse was decommissioned in 1898, the name "Nakkehoved lighthouse" has come to refer to only the western tower, which is still operational. The lighthouse marks the entrance to the Kattegat sea, and parallels the Kullen Lighthouse in Sweden on the other side of the Øresund strait. The tower is 21 meters tall emits 3 blinks of 0.3 second duration every 20 seconds. The light has a brightness of 229,358 cd, and can be seen from 25 nautical miles (ca. 46 km) away in clear weather. On the site there is also an automated weather station, restaurant, and since May 15, 2005, a Museum of International Lighthouse History. Until the end of the 18th century, only three lighthouses in Skagen, Anholt, and Kullen guided the shipping route through the Kattegat. Two towers were proposed instead of one so that sailors could differentiate them from the lighthouse in Kullen, and a royal resolution on December 10, 1770 ordered their construction on the Nakkehoved cliffs. Both were designed by the architect G.D. Anthon and built at the king's expense. By 1772, both of the towers were completed. They were originally 9 and 7.5 meters tall and lit by coal fires in iron baskets at the top of each tower. The original lighthouses were located roughly 2 kilometers west of the town of Gilleleje at the coordinates: The two towers were initially only operational from April 1 to August 31, 1772, and were shut down due to tax disputes. The towers were not relit until 1800, when maritime pilot Poul Løvenørn began to use the towers to experiment with lighthouse technique. The coal fires were converted into closed lanterns to accommodate his research. In 1833 both towers were rebuilt to run on oil and mirror apparatuses were installed. The western tower was fitted with 18 mirrors and lamps, while the eastern tower had 8. The eastern tower was decommissioned in 1898 and later refurbished to its state in 1800. It is now one of the few preserved coal-burning lighthouses in the world. Following the eastern tower's decommission, the western tower was raised to its current heigh of 21 m and refitted with a rotary lens and 6-wall burner.
