Fortress Visit Report : Portsmouth Bastion

Before my recent visit to Portsmouth, I was researching the town, I could not find any hint of fortification of the town but I found reference to a 17th century gate. This is the gate.


A very fine, elegant, yet simple, gate it is. On the wall beside it there is a plaque that explains the gate had been resited.


This shows the 17th century bastioned fortification was in four layers.

First - an enceinte comprising of five bastions and a demi-bastion and a curtain wall. The river frontage used the existing Tudor defences and casemated artillery positions, the Round Tower and the Square Tower.

Second - four ravelins or demi-lunes and a counterguard in front of King's Bastion.

Third - a continuous covered way.

Fourth - two free standing demi-lunes and a free standing redoubt.

Most of the work was demolished by the Victorians but the King's Bastion was still standing, so I went for a look. these are some photos.
