Stones from King Henry VIII's long-lost Sandown Castle have been discovered incorporated into Dover Castle, according to a new study. The 16th-century fort, which succumbed to coastal erosion, had its valuable stones reused in various projects, including parts of Dover Castle approximately nine miles down the coast.
Archaeologists uncovered a previously unknown report from 1883 detailing the sale and transport of materials from Sandown Castle to Dover. These repurposed stones now form part of the Constable's Gate at Dover Castle, which once served as quarters for the commanding officer. While some stones from Sandown were previously traced to other sites like Eastry Union Chapel and Deal's second pier, this connection to Dover Castle had remained unnoticed until now.
Sandown Castle was one of three state-of-the-art forts commissioned by Henry VIII in response to increased tensions with France and the Holy Roman Empire following his break with the Catholic Church. Built for the equivalent of over £22 million today, these 'Castles of the Down' were intended to protect a critical landing point on the Kent coast. Sandown featured a large keep and four circular bastions, equipped to house numerous artillery pieces.
Despite its formidable design, Sandown Castle never faced direct invasion. Its downfall came not from conflict, but from rapid coastal erosion. By 1785, the sea began to breach its defenses, and by the 1860s, the entire structure had to be abandoned. The upper levels were demolished, and the foundations were encased in concrete, while remaining stones were sold off for other construction purposes.
Dr. Moore, whose research uncovered this link, noted the significance of the find, stating that it provides a tangible connection across centuries and sheds light on how Dover Castle's 19th-century additions incorporated masonry from an earlier Tudor fortress. The study highlights that while Sandown Castle is primarily remembered as a casualty of erosion, parts of its structure have endured in Dover Castle and other locations across East Kent.
