Question: Which catherdral is located in London, Norwich Cathedral or St Paul's Cathedral?
Context: Norwich Cathedral is an English cathedral located in Norwich, Norfolk, dedicated to the "Holy and Undivided Trinity".  It is the cathedral church for the Church of England Diocese of Norwich and is one of the Norwich 12 heritage sites. The trompette militaire is a loud majestic sounding organ stop, with brassy, penetrating tone.  It is noted for its installation in Liverpool Anglican Cathedral, on the fifth manual of the Henry Willis Organ in St Paul's Cathedral, London, and in the 1968 rebuild of the organ of Exeter Cathedral.  At St Paul's, the stop was a gift of Henry Willis at the time of the 1930 rebuild, the pipework being bought in from America and placed with 30 inches of wind pressure in the North East Quarter Gallery in the Dome.  The Liverpool trompette militaire was the gift of Professor Alan Dronsfield and was installed in the Corona gallery, 100 ft above the cathedral floor, in 1997.  Until comparatively recently, the organ of Exeter Cathedral also had a trompette militaire in the minstrels' gallery above the nave.  In the most recent rebuild of the Exeter instrument the stop has been renamed simply "trompette" and has been complemented with a diapason chorus forming a nave division, all playable from the main console on the medieval screen.

Norwich School (formally King Edward VI Grammar School, Norwich) is a selective English independent day school in the close of Norwich Cathedral, Norwich.  Among the oldest schools in the United Kingdom, it has a traceable history to 1096 as an episcopal grammar school established by Herbert de Losinga, first Bishop of Norwich.  In the 16th century the school came under the control of the city of Norwich and moved to Blackfriars' Hall following a successful petition to Henry VIII.  The school was refounded in 1547 in a royal charter granted by Edward VI and moved to its current site beside the cathedral in 1551.  In the 19th century it became independent of the city and its classical curriculum was broadened in response to the declining demand for classical education following the Industrial Revolution.

The Dean and Chapter (or "Greater Chapter") was made up of a large number of priests who would meet "in chapter", but such meetings were infrequent and the actual governance was done by the Administrative Chapter headed by the dean, made up of several senior "residentiary canons", who were also known as the "Dean and Canons of St Paul’s" or simply "The Chapter".
