This most recent addition to Budapest’s metro lines – officially launched in 2014 – impresses many passengers with its cavernous concrete spaces and sparkling glass surfaces, and it’s continuously in the spotlight of numerous photo projects. Currently running between the Keleti Railway Station and Kelenföld Railway Station, the green line intersects both Metro line 2 (at Keleti Railway Station) and line 3 (at Kálvin Square), in addition to transporting passengers to other important locations, including Fővám Square – home to the Great Market Hall – on the Pest side, and Szent Gellért Square on the Buda side, a riverfront plaza towered over by the Art Nouveau Gellért Hotel.
