Wenlock Priory, Much Wenlock

A Monastery ^[1] was founded at Much Wenlock in 680 by Milburga, daughter of King Merwald, and niece of Wolphere, King of Mercia. She served as abbess, and after her death she was buried there. It was destroyed several times by the Danes, but was refounded by Leofric, Earl of Chester, in the time of Edward the Confessor, and again after a further destruction by Roger de Montgomery, ^[2] in 1079-82 as a Cluniac abbey. Its church was dedicated to St Mildred.

[1] Apparently it was customary to apply the term “Monastery” to a house of either monks or nuns.
[2] There seems to be some dispute as to who actually was responsible for the founding of the Cluniac Abbey, or at very least, what his title was. Timothy Gregory, who in 1824 published Gregory's Gazetteer of Shropshire, names him as Roger, Earl of Arundel, Chichester, and Shrewsbury, “a person of vast possessions in those parts, so says William of Malmsbury; but both Brompton and Leland attribute its restoration to Warine, Earl of Shrewsbury”.
