Rogerius is located at the western end of the city, near Borş, on the Hungarian border. It is the city's largest district other than the city centre, and is home to many communist-era housing estates, as well as a large market. You can get to Rogerius by tram from the city centre and other parts of Oradea, as well as by bus. It is also the first part of Oradea visitors will see when coming from Western Europe or Hungary through via Borş. The western part of Rogerius has factories from Communist times, including a chemical factory called "Sinteza".
