Óbuda was a city in Hungary that was merged with Buda and Pest on 1 January 1873; it now forms part of District III-Óbuda-Békásmegyer of Budapest. The name means Old Buda in Hungarian (in German, Alt-Ofen). The name in Croatian and Serbian for this city is Stari Budim, but the local Croat minority calls it Obuda (the name "Budim" they use for the fortress in Buda).
