A Gaeltacht is an area where the Irish language is spoken. Unlike the traditional Gaeltacht areas in the Republic of Ireland, Belfast's Gaeltacht Quarter does not have legally defined geographical boundaries. The Quarter serves as a socio-linguistic hub focused on the Falls Road/Andersonstown Road corridor in the west of the city, and aims to promote Irish language and Irish culture in the area and to develop associated tourist attractions.
