Description

The Garden Terrace at St John's College, formerly known as Ty-to-Maen, is a terrace made of snecked rock-faced sandstone in grey and red, featuring decorative elements and ashlar dressings. It includes a stepped retaining wall with saddleback coping that extends on either side of a canted bay. This bay has a parapet made of pierced masonry designed with quatrefoils and overhanging coping. At the end of each section of the wall, there are piers with wide moulded caps. Additionally, a pair of piers flanks each flight of steps that descends to the lawn, which runs parallel to the wall.
