Penrith Castle, known as the Castle of the Kings, features striking sandstone remains situated in Castle Park on the southern edge of Penrith in Cumbria. Built at the end of the 14th century by Ralph Neville to defend against Scottish incursions, the castle was later transformed into a luxurious residence by Richard, Duke of Gloucester, who became Richard III. The castle walls survive to their full height and are accessed via a wooden footbridge spanning the moat, with free admission maintained by English Heritage and extended hours during summer months from the surrounding parkland.
