Kustaanmiekka strait

In 1976 there was carried dredging works and some parts of the battery №1 was seriously damaged, in particular - its three-meter thick parapet. In general, there was a problem here early in 1914, with Sveaborg based steel battleships 'Gangut' type. In 1915 the battleship 'Sevastopol' broke all the telephone wires at the bottom of the strait when she went down the strait. It was at this time when the battery was disarmed and withdrawn from the staff.
