The Black Gate,

The Black Gate is situated to the South East of Semper as part of the Outer Wall, and is one of eight Gates in the wall.

It is a large two piece door constructed of a Magnesium Nano-composite metal gate built into a defensive tower.

The tower rises 3 metres above the surrounding wall.

The tower is constructed from polished black Diorite and is topped by a rampart with a firing step on three sides.

The tower is further fortified with a continuous Machicolation to the front and sides, at the same height as the wall. There is a firing platform inside the tower with wide openings to the front and sides of the tower allowing for a 180 degree firing arc to the front. The top rampart is accessed from steps inside the tower.

The gate is overlaid with polished obsidian which gives the gate a shiny, reflective appearance in contrast to the dull, matt black of the tower it is built into.

Passage through this gate is limited, but allows access to the ......... part of the Exterior
