The original hospital, Belmont House, was opened in 1952 by the Brothers of St John of God to provide a safe place for men to receive care for a mental illness. Today, it is one of Sydney’s most renowned private psychiatric hospitals that provides a safe, structured and supportive place to recover.
The historical narrative of Belmont House spanning 125 years was illuminated by the retrieval of a time capsule situated beneath the foundation stone of the 1892 mansion.
Mr. Adrian Howie, the grandson of the original builders, and Mr. Neil Renaud of the Colo Shire Family History Group unearthed a Gazette article from March 1892, meticulously detailing the inclusion of a time capsule during the laying of the foundation stone.

Following extensive efforts and diverse methodologies, builder Mr. Jeffrey Menzies successfully located the time capsule—a glass stoppered bottle embedded in a trench beneath the foundation stone.
Contained within were contemporaneous newspapers, a scroll cataloguing the names of all attendees present at the foundation stone laying on February 29, 1892, and a collection of "all the coins of the realm," totalling 88 coins from various corners of the globe.
