City United Reformed Church is a Grade II*-listed building located in Windsor Place, Cardiff.

[1] The church was designed in a Neogothic style by the Scottish architect Frederick Thomas Pilkington, and originally belonged to the Presbyterian denomination.

[1] The same architect was also responsible for Barclay Viewforth Church in Edinburgh.

Pilkington made a point of using local materials and created a gabled roof with an octagonal spire.

In 1893, the west front was redesigned by another architect, E. M. Bruce Vaughan, who built a new porch.
