Church Of The Holy Trinity

The Church of the Holy Trinity is a parish church located on Alford Road in Bilsby. It dates from the 15th century, with some mid-18th century alterations. The building is constructed from squared greenstone rubble, red brick, and render, featuring ashlar dressings and slate roofs. It comprises a western tower, nave, chancel, south porch, and north aisle.

The 18th-century tower has two stages, a plinth, a plain band, and a corbelled embattled parapet, with the upper parts made of brick. Atop the tower is a wrought iron weather vane. The tower includes single pointed belfry lights on all four sides and an 18th-century west window with three lights and a semi-circular head. The north aisle features banded work and render, with a small oblong light to the west. The north wall has two semi-circular headed lights with plain surrounds, imposts, and key blocks, while the vestry contains a smaller similar window. The east window of the chancel is from the 15th century, partly recut, and has three lights. The south wall of the chancel features a central 15th-century priest's door with a continuously moulded surround and a small head at the top, flanked by two 15th-century windows with flat heads and hood moulds. The south wall of the nave has three semi-circular headed lights similar to those in the north aisle, and the nave corners are accented with rusticated quoins.

The gabled south porch has a pointed outer doorway with reused dogtooth moulding in the arch, and two corbel heads are reset over the imposts. The inner doorway features a continuously moulded pointed surround.

Inside, the church has a 15th-century three-bay north arcade with octagonal piers and capitals, and double chamfered arches. The plain tower arch is semi-circular headed, while the chancel arch has octagonal responds and a double chamfered arch. In the east wall of the north aisle, there is a pointed door leading to the vestry, and a statue niche with an ogee head at the east end of the nave. A trefoil headed piscina is located in the south nave wall. In the chancel, there is a 19th-century pointed arch leading to the organ loft, along with another piscina in the south wall. Most fittings are from the 20th century, except for the 19th-century octagonal font with a pillared base.
