Norwich Cathedral is an Anglican cathedral 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 cathedral was begun in 1096 and constructed out of flint and mortar and faced with a cream-coloured Caen limestone. An Anglo-Saxon settlement and two churches were demolished to make room for the buildings. The cathedral was completed in 1145 with the Norman tower still seen today topped with a wooden spire covered with lead. Episodes of damage necessitated rebuilding and the stone spire was erected in 1480. The bosses of Norwich Cathedral are one of the world's greatest mediaeval sculptural treasures that survived the iconoclasm of the Tudor and English Civil War periods.The bosses in the cloisters include hundreds that are carved and ornately painted.
Norwich Cathedral has the second largest cloisters in England, only exceeded by those at Salisbury Cathedral. The cathedral close is one of the largest in Europe and has more people living within it than any other close.
