Some time in the early 12th century, a castle was built within the town. Originally a wooden fort built by Richard de Redvers, first cousin to King Henry I, it was rebuilt in stone by Baldwin de Redvers to resist King Stephen during the civil war with the Empress Matilda. The castle again saw action during the Civil War of 1642–1651 when occupied by the Parliamentarians. Christchurch changed hands a number of times: originally under Royalist control, it was captured by Sir William Waller's Parliamentary army in 1644. Lord Goring briefly retook the town in 1645 but was obliged to withdraw and returned with a larger force days later and laid siege to the castle. However, the Parliamentarians withstood the siege and maintained their hold on the town. Fearing such a powerful stronghold might once again fall into Royalist hands, Cromwell ordered the castle to be destroyed in 1652.&lt;ref name="Stannard p135/136"&gt;Stannard (1999) pp. 135–136.&lt;/ref&gt;
