March 2007 some of the glass was loaned to the Schnütgen Museum in Cologne for their exhibition of 16th-century German stained glass. Monuments These include an inscription on a plaque on the tower to the memory of Robert Cadman, a tightrope walker who was killed in 1739 when his rope broke. Also in the tower is a recumbent effigy by Richard Westmacott junior depicting Col C. R. Cureton who was killed in India in 1848. Inside the west entrance of the nave is a brass upon marble plaque memorial to men of the 85th Regiment of Foot who died serving in the Afghan War of 1879–80. In the north transept is a wall memorial to Rev John Brickdale Blakeway, vicar of the church, and a local historian, who died in 1826. Also in the north transept are memorials to Nicholas Stafford, who died in 1473, and Admiral Benbow, (sculpted by John Evan Thomas and unveiled 1843) who died of wounds in 1702. The oldest memorial in the church stands in the arch between the chancel and Trinity Chapel. It is a tomb chest with the effigy of a knight, and probably dates from the 1340s. In the south aisle is a grave slab from about 1100 carved with a cross and interlacing. Trinity Chapel contains separate stone tablets to men of the Shropshire Yeomanry who died in the World Wars, besides a roll of honour listing names of those who died in the Second, and a sandstone parish war memorial, headed by a crucifix, to parishioners who died during World War I, with a list of names that include VC recipient W. N. Stone. Katherine Harley, a Suffragist, is also commemorated on the memorial; she was killed at Monastir in 1917, while nursing Serbian refugees. Katherine trained at the Royal Salop Infirmary adjacent to St Mary's; she was the sister of both Field Marshal Sir John French and the Irish Nationalist Charlotte Despard. Churchyard The churchyard contains the plain sandstone war memorial cross to Shrewsbury townsmen who died in the two World Wars, erected 1920 after World War I by the "National Association of Discharged Sailors and Soldiers (Shrewsbury branch)" (predecessor of the British Legion). On corner posts of the stone kerbs are listed battles or campaigns from World War I in which the men died. Dr Samuel Butler, headmaster of Shrewsbury School and later Bishop of Lichfield, is buried
