The main attraction, and namesake, of the Old Gum Tree Reserve is the famed Old Gum Tree. It is generally considered to be the birthplace of South Australia as the uniquely shaped tree provided the setting and shade for the proclamation reading on December 28, 1836.
Legend has it that the tree, which is thought to be a red gum, was blown over in a storm and continued to grow with a curvature. Now, the remnant of the Old Gum Tree is a valued monument that serves as a reminder of the past.
The tree has long since passed but it is preserved by a concrete casing that was constructed in 1963. A protective canopy was created in 1988 to shelter the relic from the weather so that future generations can visit and view the historic site.
Two small disused cannons stand sentry by the Old Gum Tree and create a sense of significance. There are seats in front of the tree that provide a place to relax and reflect on times gone by.
The Old Gum Tree Reserve is a popular tourist attraction and school excursion.Proclamation Day is celebrated and recreated at the site each year with the current governor delivering the same speech that established South Australia as a colony all those years ago.
