During our tour of Landguard Fort we were allowed to have access to the upper levels. These provided amazing views across the barracks (officers above, men below) towards the Port of Felixstowe container port. The channel for ships entering (or leaving) Harwich brings vessels close to the walls (and guns) of Landguard (note the position of the Stena Line ferry). The large arches on the left of the picture are the gun casemates, positioned to dominate the harbour mouth.
