Óbuda (sometimes written in English as Obuda) was a historical city in Hungary. United with Buda and Pest in 1873 it now forms part of District III 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).
