From the weekend home of the British Royal Family to fully moated fairytale castles and battle scared ruins, there are over 50 castles to discover in South East England. The South Coast has historically always been vulnerable to attack from foreign attack so more than 30 of these protected and defended the UK's shores.
It is no surprise therefore, that castles in Kent and castles in Sussex dominate our guide as Kings and Queens throughout the ages turned South East England into the fortress of Britain, by building some of the most impressive, imposing and famous castles in England. Built to last, the castles make fascinating places to visit and the South East has them in abundance. From winding staircases, secret tunnels, ramparts , ornate rooms, hideaways, knights, stories of Kings and Queens and more - dive into South East England's 185 million years of history.
The south coast has historically been Great Britain's first line of defence against attack and military invasion so there are many more to explore beyond out top ten guide.
The Redoubt Fortress in Eastbourne is a unique Georgian fortress built to keep Napoleon's armies out of Britain and was in operation during both world wars in the 20th Century. The fully moated, story book Bodiam Castle in 1066 Country offers some of the best views over Sussex from the top of its towers.
The ruins of Odiham Castle date back to the signing of the Magna Carta while Southsea Castle was constructed under the reign of King Henry VIII. A more recent construction, Fort Nelson near Fareham is a superbly restored Victorian Fort with a display of more than 350 guns and daily gun salutes.
Henry VIII's chain of coastal defences also includes Walmer Castle while the river Medway into London has been stoutly defended over the years by the turreted Upnor Castle and the great keep of Rochester Castle, one of the UK's best preserved examples of Norman architecture.
