in the centre of which is a D-shaped bastion with embrasures for three guns. In the northwest corner is a defensible building of three ranges. The central one facing the ditch consists of guardrooms, between which the main entrance of the fort passes in a passageway, having crossed the ditch by means of a bridge. The northern range is a barracks for the ordinary soldiers and the southern range contains various storerooms. Further along the northern edge is the officers' quarters and the main magazine, now with a modern accommodation building over it. The gun battery is at the eastern end of the fort on the cliffs overlooking the haven. There are seven positions intended for 68-pounder guns firing en barbette (i.e. on open mountings firing over a parapet), the southernmost four being on a higher level than the other three. Originally there was an expense magazine to support these positions, but it has been demolished. The site of the Dynamite Gun position is close to the present dining area, towards the north of the fort.
