Barbette 


Needles Battery 
Portsmouth Fortifications
A view of a 9 inch RML mounted in a Barbette. This is the semi circular wall that partially protects the gun and loaders. The gun is traversed around the Barbette on the forward wheels and around a rear pivot formed by an old cannon mounted vertically in the ground. This is a Class 'D' mounting, an arrangement where the pivot is to the rear of the carriage not in the centre.
