12" batteries

The heavy 12-inch (30-cm) Obuhov cannons had a range of 45 km. The impressive pieces have barrels weighting 50 tonnes, which would be replaced after a certain amount of firing. Two cannons out of the original four remain here, the other two were transferred to the archipelago outside Vyborg in the 1930s (which was back then part of Finland) and as such they were effectively returned to Russia when WWII was over. If climbing up the cannon which is further east (halfway on the road between the harbour and hotel), you can see the Bengtskär lighthouse in clear weather.
