A predominantly Perpendicular Gothic parish church on the site of an Anglo-Saxon foundation, promoted to cathedral status in 1914 when the Diocese of Sheffield was created. The east end and parts of the tower survive from the medieval church; most of the rest is 15th- or 19th-century, with a striking 20th-century extension on the south side that includes the Te Deum window — modern abstract stained glass washing the nave with colour.
Free entry, open most days, with regular concerts and lunchtime recitals. The pre-Conquest carved cross-shaft displayed inside is one of the earliest pieces of Christian sculpture in the north of England. The Cathedral tram stop is right outside.
