Worcester Priory.
What is now the Cathedral was founded in 680 as a Priory, with Bishop Bosel at its head.
The first priory was built in this period, but nothing now remains of it.
The crypt of the present-day cathedral dates from the 10th century and the time of St Oswald, Bishop of Worcester.
Monks and nuns had been present at the Priory since the seventh century (see Bede).
The monastery became Benedictine in the second half of the tenth century (one author gives the time range 974-977, another considers 969 more likely).
There is an important connection with Fleury Abbey in France, as Oswald, bishop of Worcester from 961 to 992, and prior at the same time, was professed at Fleury and introduced the monastic rule of Fleury to Worcester.
Remains of the Priory dating from the 12th and 13th centuries can still be seen.
The Priory came to an end with King Henry VIII's Dissolution of the Monasteries, and the Benedictine monks were removed on 18 January 1540 and replaced by secular canons.
The former monastic library of Worcester contained a considerable number of manuscripts which are, among other libraries, now scattered over Cambridge, London (British Library), Oxford Bodleian, and the Cathedral library at Worcester of today. 
The Worcester Fragments comprise 25 short pieces of vocal music.
They are referred to as "fragments" because they do not exist in one unified manuscript but have been reassembled from sheets used as book-binding material in later centuries.
These old materials had themselves at some stage been bundled together into several collections of flyleaves and saved in various books which had historical connections with Worcester.
Once it was recognised that these scattered fragments came from the same source it was possible to piece them together, though much remained missing.
The pieces are from the late 13th century to early 14th century.
None of them is longer than five minutes, some as little as one minute long.
They demonstrate a variety of musical forms from the period, including the conductus and motet.
Parts of several polyphonic compositions attributed to Willelmus de Winchecumbe are included in the Worcester Fragments.15 original leaves of the Worcester Fragments were recovered from late-medieval bindings of Worcester Cathedral Priory and arenow at the Bodleian Library in Oxford. 
Along with the destruction of the monasteries, some of them many hundreds of years old, the related destruction of the monastic libraries was perhaps the greatest cultural loss caused by the English Reformation.
Worcester Priory (now Worcester Cathedral) had 600 books at the time of the dissolution.
Only six of them are known to have survived intact to the present day.
At the abbey of the Augustinian Friars at York, a library of 646 volumes was destroyed, leaving only three known survivors.
Some books were destroyed for their precious bindings, others were sold off by the cartload.
The antiquarian John Leland was commissioned by the King to rescue items of particular interest (especially manuscript sources of Old English history), and other collections were made by private individuals; notably Matthew Parker.
Nevertheless much was lost, especially manuscript books of English church music, none of which had then been printed.
In 1113 the manor of Monksilver, near Williton in Somerset, was given by Robert de Chandos to endow his new priory.
Until the 14th century the manor was called Silver, but thereafter it was called Silver Monachorum or Monksilver because of its ownership by the Priory.
"Robert de Chandos was followed by his son Robert, who died in 1120 and was buried on the south side of the choir in Goldcliff parish church.
The community was a sizable one at times—there were 25 monks in 1295, and still eight towards its close.
It also supported secular chaplains to assist with its work, with four of these in 1297.
Unusually, as at the modern communities of Prinknash and Farnborough, the monks at Goldcliff wore white habits.
This was in contrast to the black ones typically worn by other Benedictine monks, like those at Ramsgate and elsewhere.
In 1322 the prior at Goldcliff was William de Saint Albin.
A series of charters exist for Goldcliff Priory, as do 13th-century accounts of how the drainage system worked.
Local farmers widely attribute the reclamation of the surrounding farmland and the construction of the large "Monksditch" to the monks.
In 1334 the prior Phillip Gopillarius ("Philip de Gopylers") was charged—along with a monk, some clergy and fifty other persons from Newport, Nash, Goldcliff, Clevedon and Portishead—with stealing wine and other merchandise from a vessel wrecked at Goldcliff.
In 1424 the prior wrote to the king about continuing coastal erosion and flooding.
The Priory walls were close to being destroyed, and ".. half the parish church of the priory was destroyed by the sea".
Henry VI granted the patronage of the priory to Henry Earl of Warwick, with licence to appropriate it to Tewkesbury Abbey.
In 1442, with the full approval of Eugenius IV, the priory was made a cell of Tewkesbury.
The revenues of the monastery did not then exceed 2,000 marks, and the priory was worth £200 a year.
The abbot and convent were bound to maintain a prior and two monks in priests' orders.
In 1445 the three monks of Tewkesbury were expelled from Goldcliff by the Welsh, although in 1447 they again took possession of it.
But their enjoyment of its revenues was short, for in 1450 the priory was granted by Henry VI to Eton CollegeThus, at the Dissolution, ownership of the parish, together with the valuable salmon fishing rights, passed to Eton College.
The Provost and Fellows of Eton were still the lords of the manor and the largest landowners in 1901.
Many archival records for the priory (and its successors as lords of the manor), such as deeds and charters for the 12th–16th centuries (mainly 16th-century copies of originals) and manorial records for the 15th and early 16th centuries, are held in the College Archives at Eton. 
Brewood Priory could be:  Black Ladies Priory, a Benedictine priory in Brewood, Staffordshire, England, dedicated to St. Mary.
White Ladies Priory, once called the Priory of St Leonard at Brewood, in Shropshire, near to the Staffordshire county border.
Both of these communities are referred to in medieval documents, especially the many extant from the reign of Henry III, as the "Priory of Brewood", without any attempt to specify which is meant - often leading to confusion.
