Széll Kálmán tér is a square in Budapest. It is one of the city's busiest transport interchanges, which is served by a station on Metro line 2, tram lines 4, 6, 17, 56, 56A, 59, 59A, 59B, 61 and bus lines 5, 16, 16A, 21, 21A, 22, 22A, 39, 91, 102, 116, 128, 129, 139, 140, 140A, 142, 149, 155, 156, 222.
Several buses head for the popular hiking destinations of the Buda hills so this square is a common meeting place for those going on excursions. It can be considered the centre of Buda, because of its traffic and the several stores around it, including Mammut, a shopping mall. Buda Castle is easily accessible from here, either on foot or by bus lines 16, 16A or 116.
