Holy Trinity Church was built in 1845-46, at the expense, (£3,600), of Thomas Carrill Worsley of Platt Hall. The Church was opened on Friday 3rd July 1846 by the Bishop of Chester. The new incumbent was the Rev. J. Currie.
The other major landowner in the district, the Anson family that owned the Birch estate, were also paying for the construction of St James Church at Birch-in-Rusholme, perhaps there was some rivalry between the landed families, both churches opening in 1846.
As Holy Trinity was built almost adjoining Platt Hall, (conveniently for the Worsley family to walk to), so it is often seen in views of Platt Fields.
The architect, Edmund Sharpe, used terracotta tiling for both the exterior and interior, a comparatively new use for this product. It did resemble stone, but some critics objected to the imitation 'stone'. The tall and graceful spire was also faced in terracotta, but this has been made by a different supplier and proved to be of poor quality, necessitating the spire to be re-built in 1912.
