This stone monument commemorates a series of 19th century police escorts which transported several hundred thousand ounces of gold from Mt Alexander to Adelaide between March 1852 and December 1853. This is one of many such monuments along the historical gold escort route between Mt Alexander and Adelaide.
The monument sits alongside Landrigan Road in Craigie, close to the Majorca Road intersection. The plaque displays the following text (note - the gold escort was between 1852-3, however this plaque displays 1862-83):
