Holy Trinity Church is in Mount Pleasant, Blackburn, Lancashire, England.

The foundation stone was laid on 11 October 1837 by Rev John Bird Sumner, then the Bishop of Chester.

[6] The completion of the tower was delayed due to lack of funds until 1853, and the intended spire was never built.

[7] In 1860 internal alterations were carried out under the direction of E. G. Paley, Sharpe's successor in the practice.

[7] At the east ends of the transepts and the chancel, the window arrangement is unusual, consisting of 2-3-2 lights, a feature more commonly found in Germany.

[7] Elsewhere are the arms of the other monarchs, going back to Edward the Confessor, bishops and other churchmen (including Whittaker), and William Whewell (one of Sharpe's patrons).

[11] The painters employed included William Birch, Benjamin West, John Brocklehurst and Samuel Driver.
