St George's Round Church was built in 1800 and is a rare circular Palladian church with a main rotunda 18m in diameter. Tours are by arrangement. Tours of the 1756 Little Dutch Church , the second-oldest building in Halifax, can also be arranged through St George's. The Cornwallis St Baptist Church has been serving African Nova Scotians since the 1830s. Walk by on Sunday morning and hear the gospel music overflow its walls.
