Description

The sloping stone sea wall, built in rubble masonry, runs from north to south between the sea lock of the former Bute East Dock and the sea lock of Roath Basin. The wall is approximately 240 meters long and up to 38 meters wide. It features grey stone steps leading to its base. At the northern end, there is a vertical section of rubble walling that connects the sloping wall to the sea wall of the former Bute East Dock. At the foot of the wall, there are five dolphins, which are timber structures with four nearly upright corner piles that slope slightly inwards and are cross-braced. These dolphins have metal plate reinforcements at the angles and are each connected to the wall by two low-level walkways. They were used for mooring ships during repairs.
