Lined with spectacular Neo-renaissance mansions and townhouses featuring fine facades and interiors, it was recognised as a World Heritage Site in 2002.

Its realization was a blend of the plans proposed by the top 3 competitors Lajos Lechner, Frigyes Feszl and Klein & Fraser.

Its palaces were built by the most distinguished architects (led by Miklós Ybl) of the time, financed by Hungarian and other banking houses.

The construction of the Budapest Metro, the first underground railway in Continental Europe, was proposed in 1870, since the capital had always been opposed to surface transport on this road.

Construction began in 1894 and was finished in 1896, so this new metro line could facilitate the transport to Városliget, the main venue of the millennium celebrations of Hungary.
