The Sebastopol Monument (also known as the Crimean War monument and the Welsford-Parker Monument) is a triumphal arch that is located in the Old Burial Ground, Halifax, Nova Scotia, Canada. The arch commemorates the Siege of Sevastopol (1854–1855), which is one of the classic sieges of all times. This arch is the 4th oldest war monument in Canada (1860). It is the only monument to the Crimean War in North America. The arch and lion were built in 1860 by stone sculptor George Lang to commemorate British victory in the Crimean war and the Nova Scotians who had fought in the war.
