The first castle in Mallow was built on the instructions of
King John in 1185. In 1282, it came into the possession of the
Earls of Desmond. Following the Geraldine Wars, the estate was confiscated by
Elizabeth I, who granted it to Sir Thomas Norrey along with the Lordship of Mallow and of surrounding country. The Desmond Castle, as it was known, fell into such bad repair that in 1585 a new castle was constructed on the same site. The fortified house dates from the 16th century and is believed to have been built by
Sir Thomas Norreys,
Lord President of Munster, who died in 1599. Following his death, his daughter Elizabeth and her husband Sir
John Jephson inherited the house, with
their family remaining in Mallow for almost 400 years. It was placed under siege by
Richard Butler, 3rd Viscount Mountgarret, in 1642 during the
Irish Confederate Wars and did not fall. It was captured in 1645 by
James Tuchet, 3rd Earl of Castlehaven. The house was badly damaged by fire during the
Williamite War and subsequently abandoned by the Jephsons. The Jephsons built the new mansion house on the site of the older castle's stable block. ==Current use==
