Leeds Castle is in Kent, England, 5mi southeast of Maidstone. A castle has been on the site since 1119. In the 13th century it came into the hands of King Edward I, for whom it became a favourite residence; in the 16th century, Henry VIII used it as a dwelling for his first wife, Catherine of Aragon. The castle today dates mostly from the 19th century and is built on islands in a lake formed by the River Len to the east of the village of Leeds. It has been open to the public since 1976.
