marketmarket town, historic and present county of Pembrokeshire (Sir Benfro), southwestern Wales. The town grew up as a walled borough at the head of navigation on an inlet of the Irish Sea, with a castle (c. 1120) that protected a route to Ireland and the local colony of English and Flemish settlers. The English king Henry I granted the town its first charter (early 12th century), and an Augustinian priory was founded about 1200. Three present churches in the town date from the 13th to the 15th century. Haverfordwest became an important town, but its castle was partly dismantled in 1644-45, during the English Civil Wars, and subsequently the town lost its maritime prosperity, mainly to Milford Haven with its deepwater harbour. Today Haverfordwest is a market centre for the surrounding rural area and a base for tourists to explore the Pembrokeshire coast. It is also the administrative centre of Pembrokeshire county. Pop. (2001) 10,808.
