Just outside the historic Cornish town of Lostwithiel, overlooking the beautiful River Fowey valley, stands one of Cornwall's most unusual medieval castles. With its almost perfectly circular walls, fascinating royal connections and peaceful countryside setting, Restormel Castle is a wonderful place to explore.

Managed by English Heritage, this remarkably well-preserved castle ruin offers visitors a glimpse into medieval life, along with beautiful views, open green spaces and centuries of Cornish history.

What Makes Restormel Castle Special?

Unlike many medieval castles, Restormel is almost perfectly circular. Its impressive stone walls surround a central courtyard, with the remains of rooms and chambers arranged around the inside.

Built in its present form during the late 13th century, the castle was designed not simply as a fortress, but as a comfortable and prestigious residence for the powerful Earls of Cornwall.

Today, visitors can explore the remains of the great hall, private chambers and chapel, discovering how this remarkable building once functioned.

One of the highlights is the wall walk, where you can climb the steps and enjoy sweeping views across the surrounding countryside and the Fowey valley.

A Castle Fit for a Prince

Restormel Castle has strong connections with the Duchy of Cornwall and Edward of Woodstock, better known as the Black Prince.

In 1337, Edward became the first Duke of Cornwall, and Restormel formed part of his extensive estates. He visited the castle twice during the 14th century, when Lostwithiel was an important centre for Cornwall's prosperous tin industry.

The castle was surrounded by a deer park and served as a luxurious retreat, offering a very different experience from the cold, defensive fortresses we often imagine when thinking of medieval castles.

By the 16th century, however, Restormel had fallen into decline. It was briefly occupied by Parliamentary forces during the English Civil War before being captured by Royalists in 1644.

Although the castle was never restored as a residence, its distinctive circular walls have survived remarkably well.
