A seven-storey building in the centre of Tetovo, a city in the west of Macedonia, stands like a border between the part of the city where the Macedonian population lives and the other where the Albanian population lives. Albanians, Macedonians, Roma, Roma, Vlachs, Hungarians, Serbs and Bosnians have all lived in the same building for years and are all in some kind of silent conflict with each other, though they still lead their lives in common as neighbours.
