St Mary's Church, Knowsley

The church was built in 1843–44 to a design by Edmund Sharpe for the 13th Earl of Derby at a cost of about £20,000 (). It was consecrated on 6 June 1844 by Rt Revd John Bird Sumner, Bishop of Chester. In 1871–72 a memorial chapel to the 14th Earl of Derby, designed by Paley and Austin, was added. It cost £3,000, which included the cost of a monument with a figure by Matthew Noble. In 1892–93 a new vestry and a new east window by Paley, Austin and Paley were built. An organ was installed in the Derby chapel in 1913. In 1981–82 the church was reordered, a nave altar was introduced, and meeting and service facilities were installed in the base of the tower.

The nave arcades are carried on quatrefoil piers with foliage capitals. The chancel arch includes carvings of Queen Victoria and the Archbishop of Canterbury. The nave is floored with 19th-century relief tiles, and there are encaustic tiles in the chapel.
