The Castle is situated on the Blackwater River at Mallow and has being home to a castle for many hundreds of years. It is famous for its white deer, descendants of the deer given to the Castle by Queen Elizabeth I. The present structure was built in 1689 and overlooks the old castle ruins. The old castle was built sometime between 1593 and 1599 on land granted to Sir Thomas Norreys, Lord President of Munster and son of Queen Elizabeth's friend, Lord Norreys of Rycote. It was later damaged in 1645 and the family built the new castle which can be seen today. This was home to the Jephson Norreys family until the 1980's when it was sold to the McGinn family of Washington D.C in 1983. Today Mallow offers private castle accommodation and can be rented for wedding parties and the gathering of friends.
