About Karang Juwana Lighthouse

Karang Juwana Lighthouse is a 14-meter cylindrical concrete tower located on a square concrete platform. It emits a white light with a single flash every 6 seconds. The lighthouse stands on a submerged bank about 2.5 kilometers northwest of the Juwana River entrance in Indonesia. Its structure includes a gallery and is painted white. The nearest port, Tuban, is 45.2 kilometers away. While the site is accessible by boat, the tower itself is closed to the public.
