cathedral in a house in The Side, who took over command at the Battle of Trafalgar (21 October 1805) after the death of Admiral Lord Nelson. Collingwood was baptised and married in St Nicholas's and each year, on 21 October, a wreath is laid in his memory in front of the monument. His body was buried in St Paul's Cathedral in London, near to that of Nelson. The cathedral is filled with beautiful stained glass. Much of the original glass was broken during the Civil War and most now dates from the 18th century onwards. St Margaret's Chapel contains the only known fragment of medieval stained glass in the cathedral, a beautiful roundel of the Madonna feeding the Christ Child. More-modern stained glass works such as in St. George's Chapel were erected in honour of two of Tyneside's late 19th-/early 20th-century industrial pioneers, who both died in 1931 within weeks of each other. Other references to industry can be found in the cathedral's stained glass, including in the Charles Parsons window, which features Turbinia, the first turbine-driven steam yacht, with which Parsons astonished the Queen's Navy at the Spithead naval review in 1897. The cathedral contains a number of memorials, the oldest being a 13th-century tomb effigy of a knight in armour, thought to be Peter le Marechal, sword-bearer to King Edward I. It is one of the oldest objects in the cathedral. Another is the Thornton Brass, a monumental brass to Roger Thornton and his wife; he was a successful merchant, three times Mayor of Newcastle, several times Member of Parliament, and great benefactor to the cathedral. This is one of the finest examples of a Flemish brass and dates from at least as early as 1441 (maybe pre-1429); it is believed to be the largest brass in the United Kingdom, and originally it covered Thornton's tomb in the nearby All Saints' Church, Newcastle upon Tyne. This commemoration to Thornton, his wife, seven sons and seven daughters can be seen fixed vertically on the far side of the High Altar, facing the east window. A horizontal replica was previously kept near the north door of the cathedral for brass rubbing purposes. Just to the north of the cathedral stands a bronze statue of Queen Victoria erected to commemorate 500 years of the Shrievalty (the jurisdiction of a sheriff) of Newcastle. Sculpted by Alfred Gilbert and unveiled in 1903, two
