The Heroes Avenue of 130 Queensland bottle trees (Brachychiton rupestris) creates a uniquely outback boulevard, remembering the men of Roma who died in WWI. The first tree was planted in 1918 supposedly in honour of Lieutenant Corporal Norman Saunders who was killed in France in 1916. That tree, outside the Post Office, near the corner of McDowell and Wyndham streets, is locally known as the Tree of Knowledge. The rest of the avenue, extending from the railway station into Wyndham Street and along Bungil Street to the intersection with Hawthorne Street, was planted by 1920.
