Ashby de la Zouch Castle was built in the 12th century. The town and castle came into the possession of the Hastings family in 1464 and William Hastings, 1st Baron Hastings enhanced its fortifications from 1473. In the English Civil War, the town was one of the Cavaliers' chief garrisons under the control of Colonel Henry Hastings, 1st Baron Loughborough and commander of the North Midlands Army. When the town fell after a long siege in March 1646, it was counted a great relief to the surrounding towns and villages.
