Goodrich Castle is a ruined medieval castle north of the village of Goodrich in Herefordshire, England, controlling a key location between Monmouth and Ross-on-Wye. It was praised by William Wordsworth as the "noblest ruin in Herefordshire" and is considered by historian Adrian Pettifer to be the "most splendid in the county, and one of the best examples of English military architecture". Goodrich Castle was probably begun by Godric of Mappestone after the Norman Conquest of England, initially as an earth and wooden fortification. In the middle of the 12th century the original castle was replaced with a stone keep, and was then expanded significantly during the late 13th century into a concentric structure combining luxurious living quarters with extensive defences. The success of Goodrich's design influenced many other constructions across England over the following years.
