Norwich also records the site of an Anglo-Saxon church in Tombland, the site of the Saxon market place and the later Norman cathedral. Norwich continued to be a major centre for trade, the River Wensum being a convenient export route to the River Yare and Great Yarmouth, which served as the port for Norwich. Quern stones and other artefacts from Scandinavia and the Rhineland have been found during excavations in Norwich city centre. These date from the 11th century onwards. Norwich Castle was founded soon after the Norman Conquest. The Domesday Book records that 98 Saxon homes were demolished to make
Norwich Castle the civil power and wealth of the city within Norfolk and was used during a procession which combined the celebration of the city's saint and the installation of the new major of the town. The Snapdragon at the Norwich Castle, known as Snap, is the last complete example of the civic snapdragon. Like all others, it was built to contain one person, its body is made of basketwork, painted with gold and red scales over a green body and red underside, while the person's legs were hidden within a canvas 'skirt'.
