The wooden doors at the gatehouse are the oldest castle doors in Britain, surviving due to being kept in a dry, enclosed environment.
The castle's stone construction began in 1067, mere months after the Battle of Hastings.
William Marshal, often called the 'greatest knight who ever lived,' died at the castle in 1219.
The site was specifically chosen for its vertical cliff drop on one side, which eliminated the need for defensive walls along that perimeter.
Henry Marten, a regicide who signed the death warrant of King Charles I, was imprisoned in the castle for 20 years until his death.
The castle features a rare example of a 13th-century 'barbican,' a fortified gateway designed to trap attackers.
The limestone used for the construction was quarried directly from the riverbank below the fortress.
The interior of the Great Tower retains significant Roman-era materials scavenged from the nearby Roman town of Venta Silurum (Caerwent).
Chepstow Castle holds the oldest post-Roman stone fortification in Britain, with its gatehouse doors dating back to the 1190s. Strategically situated on a limestone cliff overlooking the River Wye, it served as a vital border fortress between England and Wales. The site showcases nearly 600 years of military architectural evolution, transitioning from Norman keep to Tudor mansion. It features four distinct baileys constructed across different centuries to expand defensive capabilities. The Great Tower remains the most significant Norman structure on the site, originally serving as the lord's residence. The castle was held by several high-profile historical figures, including William Marshal, 1st Earl of Pembroke. During the English Civil War, the fortress endured two major sieges before its eventual decline. It is currently managed by Cadw, the Welsh historic environment service. The site preserves original timber beams that have been dendrochronologically dated to the late 12th century.

Wear sturdy walking shoes with good grip, as the terrain features steep, uneven ground and spiral stone staircases.
Check the official Cadw website for event schedules, as the castle frequently hosts historical re-enactment groups.
Bring a picnic to enjoy in the grassy outer wards, which offer views of the Wye Valley.
Do not attempt to walk down the cliff edge toward the river, as there is no accessible path and the ground is unstable.
Closed occasionally for private events or extreme weather; check the Cadw website for seasonal site status updates.
Avoid climbing or leaning on loose stonework; remain on marked pathways to preserve the ruins.
