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.
