Macquarie Mausoleum Set in a grassed area surrounded by a circular stone wall with wrought iron gates, the Macquarie Mausoleum is a plain sandstone structure with two marble panels enclosing the entrance doorways. It holds the remains of Lachlan and Elizabeth Macquarie and their children, Lachlan – and Jane, who died in infancy. For many years the mausoleum was sadly neglected. But in 1948, Lady Yarborough, the owner of a nearby estate, gifted the mausoleum site to the people of New South Wales. Today, the tomb is preserved and protected by both The National Trust of Scotland and The National Trust of Australia. In 1851 the Drummond family, a socially prominent family, built a final mausoleum on the site.
