About Terneskjæra Lighthouse

Also known as: Terneskjæra (Terneskjærene)

This 6-meter lighthouse stands on a tiny skerry off the northeast coast of Kirkøy, opposite Singløy. Its structure features a white lantern with a red roof, supported by a platform on four black piles. The light emits three flashes in a WRG sequence every 10 seconds, with a focal height of 5 meters above sea level. Its geographic range extends to 8.4 nautical miles. The site is accessible to the public, though the tower itself remains closed.

Why it matters: This lighthouse is essential for guiding eastbound and westbound vessels around the skerry, preventing them from grounding on submerged hazards through its directional light sectors.
