Crypto lighthouses: Crypto Lighthouse 03 - Aniva Lighthouse (Russia)
Abandoned lighthouse at Cape Aniva, Sakhalin Island (Russia), on Sivuchya rock. The height of the tower is 31 meters, the height of the light is 40 meters above sea level.
The Aniva lighthouse was installed in 1939 on a small rock Sivuchya, near the hard-to-reach rocky Aniva Cape. This area is replete with currents, frequent fogs, underwater rocky banks. The Japanese name of the cape - Nakashiretoko (Jap.) - gave the original name to the lighthouse; it was later renamed Aniva Lighthouse. The author of the project was engineer Shinobu Miura (Japanese), a graduate of Kanagawa Prefecture Technical College.
It was built for more than two years: from June 1937 to October 1939. The lighthouse belonged to the third class: its lens had a focal length of 500 mm and a diameter of 1000 mm; there was an auto phone.
The lighthouse is a round concrete tower with a small side extension built into the oval base. The tower has 9 floors. On the basement floor, there were diesel and battery. The first floor with an annex was occupied by a kitchen and a food warehouse, the second - by a radio room, control room, and watch room. On the third, fourth, and fifth floors of the tower, there were living rooms designed for 12 people. In the central part of the tower, there was a pipe, inside which a pendulum was suspended - a weight of 270 kilograms, wound up every three hours to move the optical system. The range of the beacon was 28.16 km (17.5 mi). In 1968, the third floor was reinforced with concrete blocks.
