The house was the home of the notable
Barnewall family for many generations. In 1570,
James Stanihurst arranged for Sir
Christopher Barnewall to hide the English Jesuit priest and martyr
Edmund Campion in the house for a period of 10 weeks to keep him from the authorities and prevent his arrest. It is during this period of hiding that Campion wrote his book
A Historie of Ireland. In 1590,
Mabel Bagenal was sent against her will to Turvey by her father,
Sir Nicholas Bagnel, to prevent her from marrying
Hugh O'Neill, Earl of Tyrone. Ultimately, Mabel escaped from the house and eloped with O'Neill, marrying him at
Drumcondra Castle near Dublin, the home of
Sir William Warren. The house continued to be owned by a branch of the Barnewall family, the Trimlestones until 1927 when it was purchased by the Counihan family along with 155 acres. The house was purchased by the Murphy Group in 1968. Dublin Corporation, under the direction of
George Redmond, then assistant Dublin city and county manager, finally gave the order for its demolition in 1987. ==Structure==
