Caboonbah Undenominational Church is a union church on the Cressbrook-Caboonbah Road, Mount Beppo, approximately 21 kilometres (13 mi) from Toogoolawah in the Somerset Region of South East Queensland, Australia. It was founded by Henry Plantagenet Somerset,[1] and built by Lars Andersen in 1905 to serve a farming community at Mount Beppo. The wooden structure was designed by Mrs Katherine Rose Somerset and takes its name, "Caboonbah", from the Somerset family homestead, Caboonbah Homestead, nearby.[2]
