Trinity Arts Centre (Formerly Church of the Holy Trinity)

The Trinity Arts Centre, formerly the Church of the Holy Trinity, was built between 1841 and 1843 to designs by Thomas Johnson of Lichfield. The chancel was enlarged in 1871 by J L Pearson, and further work, including a vestry extension on the southeast side of the chancel, was completed in 1911 to designs by William Scorer and Henry Gamble. The building became redundant in 1973 and was subsequently converted to an arts centre between 1982 and 1984 by T R Benton of Sleaford.

The church is constructed of stone and is cruciform in plan, comprising an unaisled nave, chancel, and large north and south transepts, along with a west tower. A brick extension was added to the south side between 1982 and 1984, featuring a low clerestory and a catslide roof that aligns with the nave; during this work, the majority of the windows were blocked.

Exteriorly, the building exhibits a plain, pre-archaeological Gothic style, characterised by narrow lancet windows and thin buttresses. The tall, slender west tower is situated within the nave, with a spire that serves as a prominent local landmark. The interior has been entirely converted for use as an arts centre and theatre, retaining the 19th-century roof as a significant feature of the theatre space.

The church was originally built to accommodate the growing population of Gainsborough, its original design featuring a small chancel, three-bay transepts, and an unaisled nave with a west gallery intended for pre-Tractarian, prayer book worship. Thomas Johnson, the architect, was responsible for building a number of churches in the Midlands.

The building is designated at Grade II for its significance as a redundant church constructed in 1841-3 in a plain, pre-archaeological Gothic style, the stone ashlar faced. The chancel enlargement of 1871 and subsequent work in 1911 and the 1982-4 conversion are also notable. The tall west tower and spire remain an important landmark within the town.
