Frankeklint Lighthouse

Oc Red/Green (directional) 5s🇩🇰Langeland Municipality, DKOperational

Frankeklint was built in 1894 as a 1-story brick keeper's cottage with a semicircular lantern room at its seaward end. The white cottage features a gray shingled roof. It stands atop a dune at the northwestern tip of Langeland. The light is directional, showing red or green, with an occulting characteristic that occurs every 5 seconds. This navigational aid has a geographic range of 12.2 nautical miles. The site is open to the public, though the tower itself is closed.

Why it matters: The lighthouse's directional red and green light is important for guiding vessels through specific channels near Langeland's northwestern point. Its design, integrating the lantern room into a keeper's cottage, represents a practical architectural solution for its location and function.
