Wikipedia has an article about the Great Fire of Warwick in which St Mary's Collegiate Church is mentioned. The article tells us:
The Great Fire of Warwick was a major conflagration that swept through the small town of Warwick, England, beginning at 2:00 p.m. on 5 September 1694 and lasting for six hours. The fire started from a spark from a torch that was being carried up High Street. The town’s small population, the close-packed nature of the environment, and the amount of combustible building material all lead to the fire’s start and spread, and the limited fire-fighting methods of the time helped transform the small torch fire into a catastrophic event.
The Collegiate Church of St Mary, Warwick was severely damaged by the fire. The fire progressed through Castle Street, Market Street, and High Street until it was halted by the 0.5 metre thick stone walls of the building that as of 2006 is the Lord Leycester hotel on Jury Street. If the fire had not been stopped by the church and struck the suburbs, it would have burnt all the way to the edge of town. The original estimates had the financial damage totaling around £90,000-£120,000 and the physical damage at around 250-460 houses, but later the Book of Estimates had the damage at 157 houses totaling between £40,000-£60,000.
On the north, west and south faces of the church tower are inscriptions about the building of the church. The inscription on the north face reads:
TEMPLUM B: MARIÆ COLLEGIATUM PRIMITUS
A ROG DE NOVO BURGO COM: WAR: TEMP: STEPH: R:
INSTAURATUM, POSTEA A THO: DE BELLO-CAMPO C: WARR
This translates to:
St Mary's Collegiate Church was first established by Roger de Newburgh, Earl of Warwick, in the time of King Stephen; then, under Thomas Beauchamp, Earl of Warwick.
The inscription on the west face, that appears to continue from the north face, reads:
EX TOTO REEDIFICATUM ANo: MCCCXCIIII
CONFLAÕNE STUPENDA, NON ARIS, NON
FOCIS PARCENTA, DIRUTUM: Vo SEP MDCXCIIII
That translates to:
In the year 1394 it was completely rebuilt, and on the 5th of September 1694 it was reduced to ruins by an amazing fire that spared nothing in it's path.
The inscription on the south face of the tower reads:
NOVUM HOC, PIETATE PUBLICA INCHOATUM, ET
PROVECTUM REGIA ABSOLUTUM EST: SUB LÆTIS
ANNÆ AUSPICIIS, Ao: MEMORABILI MDCCIIII
That translates to:
The new church was built by charity, public to begin with, royal in the later stages, and was completed, under the happy auspices of Queen Anne, in the memorable year of 1704.
The Britain Express website tells us about St Mary's Collegiate Church:
The historic church of St Mary was founded as a collegiate church (administered by a 'college' of a dean and canons) in 1123 by Roger de Newburgh, second Earl of Warwick. The style of Newburgh's church was decidedly Romanesque, with heavy, rounded pillars. The best surviving part of that Norman church is in the lovely crypt.
The early Norman church was rebuilt in the 14th century by Thomas Beauchamp, father and son, the first Beauchamp Earls of Warwick. The first Thomas Beauchamp financed his building of the chancel with money obtained from the ransom of a French archbishop. The chancel, vestries, and chapter house were rebuilt in delightful Gothic style, making of St Mary one of the most attractive town churches of its day. The alabaster memorial to Thomas, who died of the plague during the siege of Calais, and his wife Katherine lies in the chancel.
The Beauchamp Chapel
But the work of Thomas Beauchamp was about to be outdone by his descendant, Richard de Beauchamp (d.1439), who provided funds in his will for the creation of a chantry chapel in St Mary's. This, aptly dubbed The Beauchamp Chapel, is one of the great Gothic architectural achievements in England. The executors of Beauchamp's will spent over £2400, an enormous sum in those days, creating a masterpiece of Gothic style which took over 20 years to complete.
The chapel, which is dedicated to Our Lady, is composed of three bays, at the centre of which is the tomb of Richard Beauchamp, raised on a pedestal and surrounded by an iron fence. The effigy of Earl Richard is set upon a chest of Purbeck marble, with a canopy above, and latten (gilded in copper alloys) weeping figures below.
Beside the tomb of Earl Richard is that of Ambrose Dudley (d. 1590), whose effigy wears a gilded iron coronet, added in the 18th century. But the grandest tomb of all in the Beauchamp Chapel is that of Robert Dudley, Earl of Leicester (d.1588), and his wife Lettice (d.1634). Dudley, the brother of Ambrose Dudley, Earl of Warwick, was a favourite of Queen Elizabeth, and one of the most powerful men in the kingdom. His tomb is set into the north wall of the chapel, beneath a gilded canopy.
You may have heard of the Great Fire of London. Well, Warwick had its own Great Fire, in 1694. The blaze destroyed much of the old medieval town, and the nave and tower of St Mary's were lost. Sir Christopher Wren, architect of St Paul's in London, submitted a design for reconstruction of the church, but Wren's design was rejected in favour of one by Sir William Wilson of Sutton Coldfield. The most striking aspect of Wilson's design is the west tower, which stands 174 feet high, and, unusually, projects out into the road, with a arches on three sides to allow passage under the tower for foot traffic. The modern road skirts around the tower arches, but one can't help but feel a trifle exposed, pausing under the tower arch and seeing traffic bearing down on the opening in which you stand!
The 17th century nave was built to give a sense of great height, something it achieves beautifully. The pillars are very high, in Perpendicular Gothic fashion. On the wall of the south aisle are two 'bread cupboards', or 'dole shelves', where, until quite recently, loaves of bread were handed out to the poor of the parish.
The small chapter house has seats for 8 canons and the Dean of St Mary's, but it is hard to see the canopied seats properly because the chamber is filled almost to the ceiling by the tomb of Sir Ffulke Greville (d.1628). Greville came from a line of rich wool merchants based in Chipping Campden, who rose to a position of prominence during the Tudor period. He was granted Warwick Castle by King James in 1604, and rebuilt much of the castle during his lifetime, before he was murdered by his manservant (see our Warwick Castle article). The tomb is quite plain, compared to those in the Beauchamp Chapel, with a sarcophagus and pillars of black marble.
An unexpected delight is the small Dean's Chapel, or vestry, just beside the Beauchamp Chapel. This small chapel has fancifully painted Gothic vaulting painted white, with blue between the vaulting ribs. Squints look through the wall of the Dean's Chapel into the much larger and grandiose Beauchamp Chapel.
Without doubt a church that deserves to be visited, St Mary's is one of the highlights of a visit to Warwick, and is easy to reach from any of the car parks in central Warwick, and from Warwick Castle (5 minutes walk). There are free guidesheets available which describe the history and major features of the church. The tower can be climbed in season, and there is a brass rubbing centre and shop in the church.
The church is Grade I listed with the entry at the Historic England website telling us:
Tower can be seen for many miles and is of high value in association with Northgate Street, also with Church Street, The Court House and adjoining buildings. Nave, transepts and tower rebuilt by Sir William Wilson in 1697-1704 after destruction in the great fire of 1694. Design supervised and perhaps modified by Sir Christopher Wren. This curious and interesting building retains much of the Gothic spirit although details and mouldings are Renaissance in character. Late C14 chancel. Norman crypt. Interior contains C18 organ case by Swarbrick and various effigies.
The Beauchamp Chapel (Lady Chapel to south of Chancel) is a very fine example of the Perpendicular style, built 1442-63 to contain the well known tomb and bronze effigy of Richard Beauchamp, Earl of Warwick (died 1439). Further interesting features of the interior include, fan vaulting, richly carved stone figures etc at east end, wall painting (Last Judgement) at west end, C15 stained glass and other tombs of the Dudley family.
