Are both, Chelmsford Cathedral and Truro Cathedral, in the same country ?
Chelmsford Cathedral Chelmsford Cathedral in the city of Chelmsford, Essex, England, is dedicated to St Mary the Virgin, St Peter and St Cedd. It became a cathedral when the Anglican Diocese of Chelmsford was created in 1914 and is the seat of the Bishop of Chelmsford.
Dean of Southwark 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.
