Gedney Hill Grade II* listed Anglican parish church is dedicated to the Holy Trinity. Dating from the late 14th century, it was heavily restored in 1874-75 by James Fowler. The restoration included the entire rebuilding of the outer walls. The arcades are supported by octagonal oak piers, and the roof by Perpendicular-style tie-beams. The stained glass east window is by Ward and Hughes. At the south of the churchyard, which also contains war graves of two airmen of the Second World War, is a listed 15th-century cross, restored in 1918.
Further Grade II listed buildings are Gedney Hill Mill and the Red Lion public house.
