The church was built in 1845–46 to a design by the
Lancaster architect
Edmund Sharpe. It was built for Thomas Carrill Worsley of
Platt Hall. The Worsley family chapel had been
Platt Chapel, but this had become a
Unitarian chapel early in the 19th century. Thomas Worsley planned to build an Anglican church, but in this he was in competition with a neighbour, a Mr Anson of Birch Hall, to build the first Anglican church in the area. Anson built St James' Church in Danes Road, Rusholme, but Worsley arranged for Holy Trinity to be
consecrated before its building was complete. Worsley chose the dedication to the
Holy Trinity to show his opposition to the Unitarians. Sharpe's first "pot church" had been
St Stephen and All Martyrs' Church, Lever Bridge. The terracotta for the body of this church was supplied, as before, by the Ladyshore Coal and TerraCotta Company, which was owned by Sharpe's brother-in-law, John Fletcher. However, there was a dispute with Fletcher about the costs; Fletcher supplied the terracotta for the body of the church, but the material for the spire was provided by a different manufacturer, Fletcher's brother-in-law, Edmund Peel Willock. The terracotta for the spire proved to be inferior to Fletcher's material, and the spire had to be replaced in 1912. In 1966–67 a church hall was built and attached to the east wall of the church. ==Architecture==
