[2] The church is dedicated to Saint Oswald, king of Northumbria, and there is a legend that his body rested on the site after he was killed in 642.
He later became vicar of Halifax, then Bishop of Meath, Lord Chancellor of Ireland, and Archbishop of Dublin.
[5] St Oswald's is constructed in rubble and ashlar limestone, and has lead and tile roofs.
[3] In its south face is a two-light window, its roof is pyramidal and it contains a small louvred gable on each side.
It is thought that these stones date from the Anglo-Saxon era and were formerly part of the fabric of the original church on the site.
[1] The arcades between the nave and the aisles are Norman in style and consist of octagonal piers, with broad square capitals and round arches.
It is constructed with Magnesian Limestone and consists of an octagonal base with a weathered shaft about 1 metre (3 ft) in height.
[2] The work of the Trust is supported locally by a group known as the Friends of St Oswald's, Kirk Sandall.
These include exhibitions, and occasional services arranged in cooperation with the local parish Church of The Good Shepherd.
