St Peter's Collegiate Church is located on the northern side of central Wolverhampton, England.
 For many centuries it was a chapel royal, and from 1480 a royal peculiar, independent of the Diocese of Lichfield and even the Province of Canterbury.
 The collegiate church was central to the development of the town of Wolverhampton, much of which belonged to its dean.
 Until the 18th century, it was the only church in Wolverhampton and the control of the college extended far into the surrounding area, with dependent chapels in several towns and villages of southern Staffordshire.

 The Collegiate Church of St Peter at Westminster, popularly known as "Westminster Abbey", is a large, mainly Gothic abbey church, in the City of Westminster, London, United Kingdom, located just to the west of the Palace of Westminster.
 It is the traditional site for the Coronation of the British monarch and many former kings and queens are buried there.
In Christianity, a collegiate church is a church where the daily office of worship is maintained by a college of canons; a non-monastic or "secular" community of clergy, organised as a self-governing corporate body, which may be presided over by a dean or provost.
 In its governance and religious observance a collegiate church is similar to a cathedral, although a collegiate church is not the seat of a bishop and has no diocesan responsibilities.
 Collegiate churches were often supported by extensive lands held by the church, or by tithe income from appropriated benefices.
 They commonly provide distinct spaces for congregational worship and for the choir offices of their clerical community.
John Robert Hall {'1': ", '2': ", '3': ", '4': "} (born 13 March 1949) is an English priest of the Church of England.
 He is the current Dean of Westminster and a chaplain to Queen Elizabeth II.
The Dean of Westminster is the head of the chapter at Westminster Abbey.
 Due to the Abbey's status as a Royal Peculiar, the dean answers directly to the Queen (not to the Bishop of London as ordinary, nor to the Archbishop of Canterbury as metropolitan).
 Initially, the office was a successor to that of abbot of Westminster, and was for the first 10 years cathedral dean for the Diocese of Westminster.
 The current dean is John Hall.
The Dean of Southwark is the head ("primus inter pares" – first among equals) and chair of the chapter of canons, the ruling body of Southwark Cathedral.
 The dean and chapter are based at the "Cathedral and Collegiate Church of Saint Saviour and Saint Mary Overie" in Southwark.
 Before 2000 the post was designated as a provost, which was then the equivalent of a dean at most English cathedrals.
 The cathedral is the mother church of the Anglican Diocese of Southwark and seat of the Bishop of Southwark.
 The current dean is Andrew Nunn.
Westminster Abbey, formally titled the Collegiate Church of St Peter at Westminster, is a large, mainly Gothic abbey church in the City of Westminster, London, just to the west of the Palace of Westminster.
 It is one of the United Kingdom's most notable religious buildings and the traditional place of coronation and burial site for English and, later, British monarchs.
 Between 1540 and 1556, the abbey had the status of a cathedral.
 Since 1560, the building is no longer an abbey nor a cathedral, having instead the status of a Church of England "Royal Peculiar"—a church responsible directly to the sovereign.
 The building itself is the original abbey church.
The Dean of Bradford is the head and chair of the chapter of canons, the ruling body of Bradford Cathedral.
 The dean and chapter are based at the "Cathedral Church of St Peter" in Bradford.
 Before 2000 the post was designated as a provost, which was then the equivalent of a dean at most English cathedrals.
 The cathedral is one of three co-equal mother churches of the Diocese of Leeds and a seat of the Bishop of Leeds; until 2014 it was the mother church of the now-defunct Diocese of Bradford and as such the seat of the diocesan Bishop of Bradford.
 The current dean is Jerry Lepine.
The Close of the Collegiate Church of St Peter was an extra-parochial area, and later civil parish, in the metropolitan area of London, England.
