The tower has been used as a coin mint, a prison, and a military storehouse. It is also famous for being the location of the wedding of Richard de Clare, the second Earl of Pembroke, and Aoife (pronounced eefa), daughter of Dermot MacMurrough, King of Leinster. It sometimes was a royal castle and was visited by King John in 1210, who ordered new coins to be made there. Richard II visited the tower in 1394 and again in 1399. He used the tower to store his munitions. On 27 July 1399, Richard left Reginald's Tower as King of England and Wales; on his arrival in England, he was captured by the future Henry IV.
