Pécs (peɪtʃ , peːt͡ʃ; Pečuh; Fünfkirchen, fʏnfˈkɪʁçn̩; also known by other alternative names) is the fifth largest city in Hungary, on the slopes of the Mecsek mountains in the country's southwest, close to its border with Croatia. It is the administrative and economic centre of Baranya County, and the seat of the Roman Catholic Diocese of Pécs.
A city dating back to ancient times, settled by the Celts and the Romans, it was made an episcopal see in early medieval Hungary. It has the oldest university in the country, and is one of its major cultural centers. It has a rich cultural heritage from the age of a 150-year Ottoman occupation. It is historically a multi-ethnic city where many cultures have interacted through 2000 years of history. In recent times, it has been recognized for its cultural heritage, including being named as one of the European Capital of Culture cities. The Roman-era Christian necropolis in Pécs was inscribed as a World Heritage Site in 2000.
The earliest name for the territory was its Roman name of Sopianæ. The name possibly comes from the plural of the Celtic sop meaning "marsh". Contrary to the popular belief, the name did not signify a single city, and there are no traces of an encircling wall from the early Roman era, only from the 4th century.
The medieval city was first mentioned in 871 under the name Quinque Basilicae ("five cathedrals".) The name refers to the fact that when constructing the churches of the city, the builders used material from five old Christian chapels. In later Latin documents the city was mentioned as Quinque Ecclesiae ("five churches", a name identical in meaning to the German name Fünfkirchen and the Slovak name Päťkostolie).
The name Pécs appears in documents in 1235 in the word Pechyut (with modern spelling: pécsi út, meaning "road to/from Pécs") most likely derives from the Proto-Slavic *pęčь or from the Illyrian *penče, both meaning five. In other languages: in Latin, Quinque Ecclesiae; in Italian, Cinquechiese; in Croatian, Pečuh; in Serbian, Печуј (Pečuj); in Slovak, Päťkostolie; in Czech, Pětikostelí; in Dutch, Vijfkerken; in German, Fünfkirchen; and in Turkish, Peçuy.
