Keri Lighthouse, Maritime navigation lighthouse on Keri Island, Estonia
Keri Lighthouse is a red metal tower standing on a stone base on an Estonian island. The structure features a lantern room and balcony that guides ships navigating the coastal waters.
A sea marker was first recorded on a nautical chart in 1695, and Tsar Peter I ordered the construction of a stone pillar in 1718. The structure evolved into the lighthouse that stands today.
The Estonian Post Office issued a commemorative stamp of Keri Lighthouse in 2003, recognizing its role in maritime navigation history.
The tower operates fully automatically and is powered by solar cells and batteries. Visitors should plan ahead since the location is remote and requires careful access arrangements.
From 1907 to 1912, this was the only lighthouse in the world powered by natural gas extracted directly from the island itself. This unusual energy source disappeared as technology advanced.
