Trondheim sits on the shores of the great Trondheimsfjord, at the mouth of the Nid river - hence the city's ancient name "Nidaros". The city centre is dominated by the magnificent Nidarosdomen (cathedral), the office of Norway's archbishop in catholic times as well as the major pilgrimage site in Scandinavia. The city centre is defined by a sharp bend of the penninsula creating a penninsula and a small estuary. The centre is characterised by straight, orthogonal streets that is the result of a major redesign (by general de Cicignon) after the devasting 1681. The city was however largely rebuilt in wood.
