About Kramat No. 7 Lighthouse

Kramat No. 7 is a green, square pyramidal skeletal tower standing 16 meters tall, with the light situated 18 meters above sea level. It is mounted on a square platform supported by piles, an adaptation for its location on a shoal. The tower emits a single green flash every three seconds, with a geographic range of 12.7 nautical miles. This structure marks the entrance to Lembar's inner harbor, located 0.9 kilometers from the nearest port. The site is accessible to visitors arriving by boat, though the tower itself is not open to the public.

Why it matters: This lighthouse warns vessels of the shoal it occupies, preventing groundings at the harbor entrance. Its construction is specifically designed to adapt to the challenging marine environment at Lembar's inner harbor approach.
