Trinity College, The Buildings surrounding Great Court, Nevile's Court and New Court, and including King's Hostel

This Grade I listed complex encompasses the historic core of Trinity College, incorporating buildings from the late 14th century through to the 19th century, representing over four centuries of collegiate architecture.

Great Court

East Range and Great Gate

The Great Gate and its flanking ranges form the principal entrance to the college. The lower stage of the gate and adjacent ranges survive from King's Hall, begun around 1490. Construction proceeded slowly until about 1505, then ceased until 1528–29. The gate tower was completed in 1535.

The gate rises to three storeys. Its east wall is built of ashlar stone, whilst the remainder is brick with stone dressings. The east front displays elaborate decoration above the arch, including coats of arms, inscriptions, and a statue of Henry VIII in a niche. This statue was begun by Paris Andrew around 1600 and completed by William Cure in 1615. The main gate was made by Buxton in 1523; the smaller gate dates from the mid-18th century.

The west front features three statues in niches—James I, Anne of Denmark, and Prince Charles—all carved by William Cure in 1615. The gate hall has a timber vault from 1845, though this sits on original springers. The adjacent ranges are two storeys with attics, roofed with stone slates and tiles. The western elevation was embattled around 1600.

The northern part of the range was comprehensively refaced by Salvin: the east side in 1856 and the west in 1935. Internally, some 18th-century fielded panelling survives, along with several exposed 15th-century beams.

South of the gate, the range dates from the late 16th century, probably completed in 1602. Windows vary from one to three lights. 18th-century lead rainwater pipes survive. Inside are 15th-century beams and panelling from around 1600 and the 18th century. The Bursary contains early 18th-century fielded panelling divided by Ionic pilasters.

North Range: The Chapel

The Chapel was completed in 1567 with Perse as mason and Stephen Wallis as joiner. It was refaced in ashlar during the 19th century and has a modern slate roof. Between 1706 and 1717, the chapel underwent repairs and refitting. Edward Blore restored it in 1832. From 1868 to 1873, A.W. Blomfield added the vestry, choir-room, and porch, and re-roofed, painted, and glazed the chapel.

The chapel extends twelve bays with a 24-bay roof. Notable features include a brass from 1565 and early 18th-century oak communion rails. The ante-chapel houses several important sculptured monuments, including memorials to Newton, Bacon, and Macaulay, with work by Nollekens, Flaxman, and R. Westmacott. The organ was built by Bernard Smith and Christopher Schrider in 1708. Very fine panelling, screen, and stalls date from around 1735. The Corinthian reredos is early 18th century.

King Edward's Tower

This tower served as the gatehouse to King's Hall. It was erected on its present site between 1428 and 1432 by master-mason John Dodington, with alterations made in 1599–1600. A clock and bells were installed in 1610 and renewed in 1726–27. The bell turret is mid-19th century.

The south face features carvings, shields, and inscriptions, including a statue of Edward III from around 1600. The interior, including the gate hall, has been modernised.

Old Library Range

This range stands west of King Edward's Tower. It is three storeys, though the library was removed from the top floor in 1694–95. The range was built in 1600–1601, burnt, and rebuilt in 1665–66. The structure comprises eight bays of clunch, rubble, and brick with five 17th-century buttresses. The windows, of two and three lights, are mostly renewals. Internally, some reused original panelling survives alongside 18th-century panelling and fittings.

West Range: The Hall

The Hall was begun in 1604, designed by Ralph Symonds and built by John Symes, with Francis Carter as master carpenter. The interior was restored in 1866 and 1955. The hall extends seven bays. The east front features a porch with attached Roman Doric columns. A hexagonal timber lantern of three storeys rises above, topped with a wrought-iron weather vane.

Inside, the original double-framed timber hammerbeam roof spans seven bays. The dais panelling is punctuated by Ionic pilasters. A two-stage screen of five bays displays Ionic and Corinthian columns from 1605–1608; the doorways and fanlights are late 19th century. The windows contain substantial heraldic glass, partly late 16th and early 17th century and partly post-1850, along with some medieval fragments.

The Old Kitchen, now a second dining room (converted in 1969), dates from 1605 and is open to the roof, with a three-bay hammerbeam structure and three large fireplaces. The Buttery and remainder of the range were remodelled by James Essex between 1771 and 1774. This section is three storeys with cellars and a slate roof. Inside is a late 18th-century staircase. The Old Combination Room features a plaster dado and other contemporary decoration.

North of the Hall, the range contains the Fellows' Parlour and Combination Room, and the Master's Lodge. This section was begun in 1554, with a rear wing added in 1892 by Sir Arthur Blomfield. The Lodge dates from 1601–13 and was improved between 1700 and 1710. The roof was renewed in 1785–86. Salvin altered it between 1841 and 1866; the front onto the court is mostly Salvin's work from 1841–43. The Master's porch dates from around 1600. The west front has restored windows from all periods.

The Master's entrance hall retains 16th-century panelling; the staircase is from 1705. The Dining Room and Judge's suite have early 18th-century bolection moulded panelling. The Drawing Room preserves its original late 15th-century plaster ceiling and a fine fireplace. Numerous other original and later features survive.

South Range

This range is two storeys with attics and features the roughly central Queen's Gate of three stages. The north front is ashlared with slate and tile roofs. Construction occurred between 1594 and 1602; the gate is dated 1597. The north front was repaired in 1753–54, with various other repairs and restorations undertaken at different times.

The gateway displays a statue of Queen Elizabeth among its external decoration. The oak door is original. The second-floor room has plain 18th-century panelling. East of the gate, the range extends fourteen bays with 18th-century lead rainwater pipes. Internally are three original staircases (L, M, and N), original and 18th-century panelling, and other features. West of the gate are ten bays, the last being an 18th-century rebuild. Various doorways, panelling, and other features survive.

King's Hostel

King's Hostel comprises part of the original buildings of King's Hall—the west range of the former inner court—making it the oldest building in Trinity College. Part was built between 1375 and 1377, with additional construction from 1416 to 1422. W.D. Caröe restored it in 1905. Access is through King Edward's Tower.

Externally, several original doorways and windows survive, though the west side has been completely restored. Internally, numerous early features remain, including fireplaces and open timber ceilings. Several rooms contain 18th-century bolection moulded or fielded panelling.

Nevile's Court

The north and south ranges were constructed between 1605 and 1612, originally three-fifths of their present length. The court was initially closed by a screen with a central gateway, probably Nevile's Gate, but this was removed with the construction of the Library from 1676 to 1695. At that time, the north and south ranges were extended to their current length and remodelled, in part rebuilt, by James Essex between 1755 and 1758.

North Range

This range is three storeys, faced with Ketton stone ashlar and modern synthetic stone. The entire ground floor is a cloister walk of round-headed arches supported on Roman Doric columns of a Brunelleschian type. Above each arch is a three-light transomed window on each floor. The range has a parapet with slated and tiled roof. James Essex transformed the top floor from the previous attic. Three staircase towers project on the north side.

Internally, various original features survive, including doorways and staircases. Staircase G dates from 1676–81; Staircase L is mid-18th century. Some original doors and late 17th-century bolection moulded panelling remain.

South Range

Little of the original construction survives except the form and basic design. The eastern extension was built by Robert Grumbold in 1681–82. Nevile's front was entirely rebuilt by James Essex in 1756–57, with the interior refitted throughout in 1758.

The north front matches the south front of the north range. The south front was restructured to become the north range of New Court, receiving turrets, battlements, Roman cement facing, and a six-arch arcade with four-centred arches. Internally, fittings are nearly all from 1758, though some earlier panelling was reused. The Old Guest Room has bolection moulded panelling from 1682 by Cornelius Austin.

The Library

The Library forms the west range of Nevile's Court. It was built between 1676 and 1695 by Sir Christopher Wren, with Robert Grumbold as mason. The ground floor features an open undercroft of eleven bays supported on Roman Doric columns. Above, the library floor displays an Ionic order above a balustraded parapet with plain pedestals, the centre four supporting statues.

Each arch on the upper floor contains a three-light window with square stone mullions and a moulded transom. The statues represent Mathematics, Physics, Law, and Divinity and are by Cibber. The west front is similar, except the lower stage is enclosed with an ashlar front featuring three doorways and ten windows with a Roman Doric order. The openings retain the original wrought-iron gates from 1691–92. The upper floor has thirteen windows. The north end is occupied by the staircase pavilion; the south end by the west range of New Court.

Internally, the ground floor is supported on a row of fourteen Roman Doric columns. The staircase pavilion features a wrought-iron balustrade, bolection moulded panelling, and a fine coved plaster ceiling. The library has panelled walls with projecting bookcases crowned with wooden busts carved by Grinling Gibbons. Marble busts stand at the end of each bookcase, though these were not part of the original scheme. A full-length marble figure of Charles Seymour by Grinling Gibbons dates from 1691.

The woodwork and carving in the panelling, bookcases, doorways, and coats of arms is of extremely high quality. The marble busts include works by Roubiliac, Woolner, Scheemakers, and Rysbrack. A seated marble figure of Lord Byron by Thorvaldsen dates from 1831. The reading tables and stools are all original. The ceiling is from 1850, though executed to Wren's original design.

The Tribunal

The Tribunal stands on the west side of the Hall, centred on Nevile's Court. It is a Roman Doric screen in Ketton stone ashlar by Robert Grumbold from 1682–83. The terrace has semi-circular steps and a stone balustrade. Four of the pedestals carry 18th-century wrought-iron lamp standards.

New Court

New Court was built between 1823 and 1825 by William Wilkins in the Tudor Gothic style. It is three storeys with attics. The river front is built of Ketton stone ashlar; all internal faces and the east front are cement-rendered. Moulded plinths and strings run at each level beneath an embattled parapet. Windows are of two lights.

The east and west gate towers have four-centred arches with pointed-segmental plaster vaults. The east, west, and south ranges follow the features described above, with minor differences and some alterations. The north range is described under Nevile's Court. Internally, many plain original features survive, along with some elements reused from earlier buildings.
