The Budapest Metro is a rapid transit system in Budapest, the capital of Hungary. It is the oldest electrified underground railway system in the world, and the second oldest underground railway system with multiple stations after the originally steam-powered London Underground. Inaugurated in 1896, the Budapest Metro is not only one of the oldest metro systems in the world, but also a testament to the city's commitment to modern urban life. With four lines in the city (M1, M2, M3 and M4), the metro network provides extensive coverage, connecting iconic sites, cultural centers and residential neighbourhoods. Renowned for its architectural diversity, the Budapest Metro stations display a mix of historical and contemporary designs, reflecting the rich tapestry of Hungarian culture.
