The tallest medieval castle tower ever built is generally considered to be the Chateau de Coucy keep, or donjon, which measured 55 m high and 35 m wide. Located in Picardy, France, it was constructed in the 1220s by Enguerrand III, Lord of Coucy, and was destroyed in April 1917 during World War I.
Castle keeps can be difficult to accurately measure, as the ground on which they stand often slopes, and/or is bordered by moats, ditches and other variable levels.
Osaka Castle in Chūō-ku, Osaka, Japan, measures 58.49 m high and was built between 1583–98. However, the building has been destroyed on two separate occasions, and the current measurable version is a concrete replica, constructed in 1995–97. It is unclear exactly how tall the original castle was.
