Fort “Grand Duke Konstantin” – one of the most significant fortifications of Kronshtadt fortress and undoubtedly, the most remarkable from the engineering point of view. For more than a hundred years, before forts “Totleben” and “Obruchaev” were constructed, fort “Grand Duke Konstantin” served the core of vanward defense line. It was constructed right to face the main attack, near southern navigating channel, which was the only possible spot for the enemy’s fleet to break-though. It was here where cutting-edge technical and engineering solutions were adopted; the newest weapons and fire control instruments were installed.
Already when it was created in 1809 Double southern battery was different from all the other structures of the fort: for the first time ever artillery battery was a double-deck construction, what allowed to double the number of weapons at the same square and significantly increase gunpower. Moreover the lower deck was safely protected from the cannon balls by breastwork of the upper deck.
In 1834 after radical reconstruction, under the Imperial edict of Nicolas I, the battery was renamed after Grand Duke Konstantin, the Emperor’s second sun, admiral and the head of Admiralty.
Fast development of artillery soon made wooden fortifications useless and right before Crimean war the fort was dismantled. On its foundation they built temporary stone battery – Navy batter №4 “Konstantin”.
Later another battery – “new Konstantinovskaya” was constructed a bit to the South-West, both batteries were united into one body and connected with Kotlin Island by the dam.
For the first time ever on Konstantinovskaya battery the army introduced armoured breastwork (of three different kinds: constructed by engineer colonel Schwede, Artillery department and Lancaster). The weapons, installed behind the breastworks, were protected from curved fire by armoured blindages. For the first time here the distance gauge invented by Petrushevskiy was used, and the data could be transferred to forst Alexander I and Paul I by underwater telegraph cable. The battery was first to be equipped by rapid-fire 6“ cannons, observing 57mm cannons by Nordenfeld and 2 unique weapons by major general Pauker, which were hidden in casemates. Before the First world war the battery Konstantin was amongst other things equipped with 2 13,5“ weapons – the mightiest in the whole fortress of Kronshtadt. 1808 – construction of Double Southern battery

Joint committee approved the district “Fort Konstantin” of marine checkpoint in “Big port of Saint-Petersburg”.
17th August 2012 the Joint committee gathered for a session in order to check conformance of reconstruction of first order of terminal for small-sized vessels and yachts (Fort Konstantin) of marine passenger-and-freight permanent multilateral checkpoint through Russian state border with technical requirements for construction and reconstruction of border and customs checkpoints. After check the members of the Committee approved the checkpoint. Project capacity of first order of Fort Konstantin was set up to 20 yachts and 100 people a day.
The committee was presided by the Head of Department for maintenance of state border objects and checkpoints administration of Russian border authority Danila Vavilov.
Joint committee also included the representatives of North-West territorial administration of Russian border authority, department of state policy in the field of marine and river transport of Russian Ministry of transport, North-West customs administration of Federal customs service, Boundary administration and Devision of border control of Federal Security service in Saint-Petersburg and Leningrad region, Agricultural control and Customer service control.
