The church is noted as having a large medieval window showing scenes from the life of St Martin of Tours. The nine metre high window was removed for safe keeping in 1940, and was not destroyed in the bombing of April 1942. When it returned it was set in the north wall rather than its original location in the west wall, as part of a wholesale reconstruction of the church by George Pace. As a result its monumental scale now dwarfs the size of the much reduced church. The east window in the former south aisle, which following rebuilding functions as the nave, was designed and manufactured by
Harry Stammers and installed in 1963. It commemorates the destruction of this and other churches in the bombing raid on York, the form of the red flames taking hold of the buildings, and the rising smoke above, creating an almost abstract appearance. The reredos screen below was designed by
