The Museum Under the Bridge is the former police station built in 1886 and has been converted to the Coonamble Historical Museum.
The museum displays artefacts, photographs, implements and household utensils used in Coonamble's early history. The 'trooper' brick horse stables have been retained in original form with stalls, feed boxes and saddlery and is one of only two of its kind left in NSW. Just recently a Cobb and Co coach was obtained by the museum and restored and loaned out for parades and celebrations.
