By 1542, Portsmouth was surrounded by defensive ramparts and towers built from earth and wood. One tower was positioned on the corner where the wall extending from the saluting platform met the wall running along the southeast rampart of the town. The southeast rampart was also equipped with what appears to be a firing platform, while another tower was constructed on the corner where the ramparts to the south east and the northeast of the town met. In the centre of the northwest rampart was the town gate defended by a structure known as The Mount which also acted as a bastion. Finally, the wall to the north of the town had a tower at each end one where it joined the northeast wall and one where it met the sea. Gabions were constructed along the edge of the Camber dock area and a palisade made to separate Portsmouth Point from the town. A wooden wall was constructed between the Round Tower and the saluting platform at around the same time.
