The Utö Lighthouse is located on the island of Utö, in Pargas municipality, Finland. The 24-metre-high (79 ft) tower is situated on the island's summit. After the original round lighthouse (Finland's first lighthouse) was destroyed during the Russo-Swedish Wars of 1808-09, the present structure was constructed in 1814, with the present lens installed in 1906.
The lighthouse is painted as the signal flag H (Hotel), as the island has a maritime pilot station. Likewise, the light signal of the lighthouse is four short flashes (....) as Morse code letter 'H'.
