Chester Castle: Agricola Tower and Castle Walls

Origins and Early Significance

Chester Castle was established in 1070 by William the Conqueror as a timber motte-and-bailey fortress to secure Norman control over the region. Over the 12th century, the castle was rebuilt in stone, with the Agricola Tower constructed as the first stone gateway. This tower remains one of the best-preserved medieval structures on site. The castle served as a military stronghold and administrative center for the earldom of Chester, playing a crucial role in regional governance and defense.

The Agricola Tower and Chapel of St Mary de Castro

The Agricola Tower is notable for its vaulted ceilings and the first-floor chapel dedicated to St Mary de Castro. This chapel contains exceptional medieval wall paintings dating from around 1240, rediscovered during restoration efforts in the 1980s. The chapel’s heavy copper-plated door, dating from its use as a gunpowder store in the early 19th century, adds to its historic character. Visitors can climb the tower and access the castle walls, gaining insight into medieval religious life and defensive architecture.

Military and Administrative Evolution

Throughout the reigns of Henry III and Edward I, Chester Castle became a key military headquarters for campaigns in Wales, with significant building work on the outer bailey. During the English Civil War, it served as the Royalist headquarters under John, Lord Byron. Later, the castle housed a permanent garrison until military withdrawal in 1999. The outer bailey was rebuilt in neoclassical style between 1788 and 1813, with Thomas Harrison’s designs transforming parts of the castle into civic buildings including the Shire Hall and courts.
