St Marys Towers is significant because of the well-known historical figures who lived there and because of the substantial two-storey Gothic revival country residence which has altered little since the additions designed by Edmund Blacket in the 1860s.
In 1842 Sir Thomas Livingstone Mitchell, Surveyor-General for the colony of New South Wales between 1828 and 1855, laid the foundation stone of his country residence Park Hall. In 1860 Park Hall was purchased by Dr Richard Jenkins and renamed Nepean Towers. Dr Jenkins added a colonnade to the northern and eastern walls of the house. He also added a small chapel. In 1868 one of the visitors to his Nepean Towers property who came by rail and then by carriage across the Douglas Park river crossing was Queen Victoria’s second son, Prince Alfred, the Duke of Edinburgh. In 1904, ownership was transferred to the Catholic Order known as the Missionaries of the Sacred Heart. They renamed the property St Marys Towers and built a number of new buildings including a substantial stone Apostolic School (now a Retreat Centre), a Church and Novitiate.
