At the mouth of the River Fal estuary, Pendennis and its neighbour, St Mawes form the Cornish end of costal castles built by Henry VIII to counter threat of invasion from France and Spain. Thereafter Pendennis was frequently adapted to face new enemies over 400 years, right through to World War II. Pendennis today stands as a landmark, with fine sea views and excellent site facilities including a hands-on discovery centre, exhibitions, a museum, guardhouse, shop and tearoom. It is also an excellent venue for special events throughout the year.
