History

It was built in 1940 to guide vessels towards the Toppila harbour.[2]

The tower is 5 metres (16 ft)-high octagonal concrete structure with an octagonal steel lantern, resting on a square slab of concrete. The tower was originally painted red with a white lantern. The light displayed a flash every three seconds, green, red or white depending on direction. The focal plane was 5.7 metres (19 ft) and the range was 6.6 nautical miles (12.2 km; 7.6 mi).

The light was noted as an active light in the 1996 List of Lights of Finland, but was not mentioned in the 2000 edition.[2] The light was deactivated in the late 1990s and nautical charts dated in 2005 shows the light marked down as a cairn.

Due to the glacial rebound the tower is located 150 yards (140 m) away from the coastline, and is almost completely hidden by the shrub. A footpath leading to the western end of the Letonniemi promontory leads next to the tower.
