Photograph of Fort Constantine at Sevastopol harbour. In the foreground there is a terrace with a stone wall reinforced with wicker fencing. On the terrace there are two cannons and a pile of cannonballs. Fort Constantine can be seen behind on a headland that extends out into the harbour.

During the Crimean War the entrance to Sevastopol harbour was defended by a number of forts. Fort Constantine was located on the northern side of the harbour.

Whilst the photograph is signed 'Robertson', it has been noted that the photographer Felice Beato was employed by his brother-in-law Robertson in the Crimea in April/May 1856. (See L. Gartlan, 'James Robertson and Felice Beato in the Crimea: Recent Findings', in 'History of Photography', 29:1 (2005), p.5.)
