A free two-hour wander of the historic site will share fascinating tales of the traditional rural showground pavilions and ancillary buildings, as well as the people associated with them.

Jan Page, a member of Bathurst Family History Group, is co-ordinating the first-ever tour, sharing how the buildings came about and some of the showground's significant happenings.

"We're going to be looking at what's happened there in the past, rather than what we know happens there," Mrs Page said.

The showground is most famous for hosting the annual Royal Bathurst Show, but has been used for agricultural, livestock, equestrian and community events since its founding in 1815.

The State Heritage listed site is a Bathurst landmark which consists of architecturally significant buildings, including the Howard Pavilion which was designed by renowned architect Edward Gell in 1879.

Extraordinary historical events for the region have taken place at the venue which are often suppressed the ongoing popularity of the ground's affairs.

"We'll be talking about 'Wizard' Stone's first aeroplane flight seen in the Central West," Mrs Page said.

"And also how in 1916 it was a military camp before it flooded out and when the Queen visited in 1954."

Showground tours can be booked through the Bathurst Visitor Information Centre as part of the town's Autumn Colours festival.
