In the 1940s the house and gardens became the property of the Christian Brothers who used it as a school for aspirants to the Congregation. The farm was run as a business at one point, as the Brothers sold carrots, cabbage, potatoes, apples, pears and plums.
In 1972 the Christian Brothers decided to leave Old Connaught, which was then sold off in sections. They sold the Walled Garden and Old Stable Yard to a Mr James Carroll, who closed the gates of the property and locked it. It was left idle for over 20 years. In 1996, Mr Carroll leased the Walled Gardens and farmyard to the Festina Lente Foundation who took on the great task of restoring the gardens.
