It has a west tower with a broach spire, a five-bay nave with south porch, a short chancel with a polygonal apse, and a north vestry.
The church and its churchyard contain works by two of England's most accomplished sculptors, Sir George Frampton and Gilbert Bayes, and has stained-glass windows designed by Robert Anning Bell.
Two of them, the sub-prior and the kitchener, attempted to re-establish the monastery following the great rising against the government of Henry VIII of England, known as the “Pilgrimage of Grace”.
Warter has several notable buildings including a row of thatched cottages and Manor House Farm built in 1732 using stone from the demolished medieval priory.
In 2011, two stained glass lunette windows by Robert Anning Bell, which had been in storage since 1966, were placed in the nave of the church following restoration.
They had originally been in a mausoleum built in the churchyard to house the remains of Lady Isabel Wilson, which also contained her marble effigy.
One of the windows depicts Lady Isabel and her dead baby being carried to heaven by six angels watched by her husband.
The other window depicts the personifications of Lady Isabel's virtues – Courage, Hope and "Love to the Death" – surrounded by child-angel musicians.
One, commemorating the 1st Lord Nunburnholme who died in 1907, is in the form of the figure of Victory with a laurel wreath, while the other, nearer the church, is in memory of his youngest son, Gerald Valerian Wilson.
