text: The seventh-century town was centred near the quay. Around 700 AD, Frisian potters from the Netherlands area settled in Ipswich and set up the first large-scale potteries in England since Roman times. Their wares were traded far across England, and the industry was unique to Ipswich for 200 years. With growing prosperity, in about 720 AD a large new part of the town was laid out in the Buttermarket area. Ipswich was becoming a place of national and international importance. Parts of the ancient road plan still survive in its modern streets.
  After the invasion of 869, Ipswich fell under Viking rule. The earth ramparts circling the town centre were probably raised by Vikings in Ipswich around 900 to prevent its recapture by the English. They were unsuccessful. The town operated a mint under royal licence from King Edgar in the 970s, which continued through the Norman Conquest until the time of King John, in about 1215. The abbreviation Gipes appears on the coins.
  King John granted the town its first charter in 1200, laying the medieval foundations of its modern civil government. Thenceforth Ipswich strongly maintained its jurisdiction over the Liberty of Ipswich, an administrative area extending over about 35 square kilometres centred on the town.
