Warnemünde harbour entrance lights, Harbour entrance lights in Warnemünde, Rostock, Germany.

The Warnemünde harbour entrance lights are two towers marking the port entrance, with one showing green light and the other red light. They guide ships safely into the harbour through a specific shipping channel.

Harbour approach lights have marked Warnemünde and Rostock since 1886. In 1896, under harbour construction director Karl Friedrich Kerner, the west mole was extended by about 130 metres and fitted with a light beacon. The east mole was rebuilt between 1897 and 1903, and the Warnemünde lighthouse followed in 1897/98. The present green-and-white west mole light was moved onto a new arm of the mole head in 1998, the same year a nearly identical red-and-white tower was erected on the rebuilt east mole.

The west mole light is a green-and-white steel tower moved in 1998 to a new arm of the mole head; the east mole light is red-and-white and nearly identical. The old east mole tower, active from 1963 to 1997, carried a Zeiss optic and the Rostock coat of arms with a griffin facing the sea. Since 2019 the restored tower stands on the roof of Bistro DECK 9 at the shipyard.

The towers are visible from nearby walking paths along the harbour front. You can view them from different angles as the area is open and accessible without barriers.

The two towers mark the boundary between two distinct water channels. The older natural river mouth runs alongside the newer artificial passage, making this spot where two water routes meet.
