Dumbarton Castle: the Spur Battery
The structure on the right was a latrine, and (because of that, I presume) it projects slightly from the curtain wall of Dumbarton Rock, as is made clear in NS3974 : Dumbarton Castle: area west of the Governor's House, where this area is shown near the upper left corner of the photograph. The opening on the left, with a grille, can also be seen in that picture.

The Rock is a volcanic plug, and it has a long history as a fortified site. For further information, see the Geograph article "Dumbarton Rock and Castle": Link
