The Kihnu Lighthouse, locally called "puak," is located at the southern tip of Kihnu Island, on Pitkänä Head. The lighthouse was built in 1864 from cast-iron parts imported from England and assembled on-site. It is one of the four remaining cast-iron lighthouses in Estonia, standing 29 meters above sea level. The Kihnu Lighthouse is white, conical in shape, and features a lantern room and a balcony. The lighthouse was renovated in 2018.
The lighthouse has played a crucial role in the island’s history, as it served as the only connection to the outside world until 1898. The Kihnu Lighthouse was first illuminated with kerosene in 1882 and has been operating automatically since 1996. The lighthouse is open for visits every day during the summer season, with an entrance fee.
