Andrássy Avenue

It opened in 1876 to link the centre with City Park, modelled on the grand boulevards of Paris. Its 2.5 km are lined with late 19th-century mansions, villas and apartment buildings, and it has been a World Heritage Site since 2002.

Beneath it runs the M1 line, opened in 1896, the oldest metro in continental Europe, with small tiled and wood-panelled stations. Along the way you pass the Opera, Oktogon, the House of Terror and, at the end, Heroes' Square.
