Thomas de Berkeley, 3rd Baron Berkeley Thomas de Berkeley, 3rd Baron Berkeley Thomas de Berkeley (c. 1293 or 1296 – 27 October 1361), "The Rich", feudal baron of Berkeley, of Berkeley Castle in Gloucestershire, England, was a peer. His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (d.1641), steward of the Berkeley estates, the biographer of the family and author of "Lives of the Berkeleys". He was the eldest son and heir of Maurice de Berkeley, 2nd Baron Berkeley by his wife Eve la Zouche. In 1327 he was made joint custodian of the deposed
Berkeley Castle from the Minstrels' gallery. His tomb is in St Mary's churchyard which stands besides the castle. Adjoining the Great Hall was the Chapel of St Mary (now the morning room) with its painted wooden vaulted ceilings and a biblical passage, written in Norman French. In the late 16th century Queen Elizabeth I visited the castle and played bowls on the bowling green. During the English Civil War, the castle still held sufficient significance for it to be captured in 1645 by Colonel Thomas Rainsborough, for the Parliamentarian side and after a siege which saw cannon being fired at point blank
