Bolshaya Muksalma (Russian: Большая Муксалма) is one of the Solovetsky Islands. Bolshaya Muksalma is situated to the east of Bolshoy Solovetsky Island and is separated from it by two straits: Severnye Zheleznye Vorota and Yuzhnye Zheleznye Vorota (literally translated as Northern and Southern Iron Gates). The Yuzhnye Zheleznye Vorota Strait is crossed by a dam which was built by the monks of Solovetsky Monastery between 1865 and 1871 and now connects the two islands. The dam is several hundred meters long and 6.5 metres (21 ft) wide. Southeast of Bolshaya Muksalma, there is Malaya Muksalma Island, as well as a number of tiny islets. The area of Bolshaya Muksalma is 17 square kilometres (6.6 sq mi).
