St John Bastion has a single 64-pdr MLR emplacement at the salient of the battery. As with the other 64-pdr emplacements on the Cottonera Lines, there are two expense lockers, one on each side. However a new structure has been built over the top of the emplacement.
It is assessed that this emplacement was built in 1876 to 1877, at the same time as the emplacements on the Floriana Lines.
