The Fitzroy Iron Works was the first Iron Smelting works in Australia, built in 1848.
Just southwest of the current Mittagong town, the original mine deposit was located just South of the Main Road. The Iron Works were established on the North side old Hume Highway and Mt Alexander.
During excavation work for a new Woolworths store in 2004, the remains of the Iron Works were found. The site was excavated and researched, and the new development was expanded to incorporate the historic artifacts. The displays are viewable in the under-ground car park area.
