Sections of the city contain numerous sectarian murals, political street art reflecting the political and religious allegiances of the communities living there. Areas such as the Shankill Road contain murals that are almost entirely Protestant, depicting republican violence, loyalty to the British Crown, the Ulster Volunteer Force and Ulster Defence Association. Conversely, murals in areas such as the Falls Road, which is almost entirely Roman Catholic, feature political themes such as a united Ireland and the Provisional IRA, as well as traditional folklore and the Irish language. The Gaelic folk hero Cúchulainn has appeared on both republican and loyalist murals, representing the heroic Celtic past for the former and legendary battles between Ulster and the other provinces for the latter. In recent years some paramilitary murals have been replaced, in both loyalist and republican areas, with less controversial images. These include murals to the writer C. S. Lewis and the late Belfast footballer George Best.
