The M1 underground line was the first underground of the Continental Europe (the first one in Europe was built in London). In 1870, the Hungarian parlament decided on building an Avenue starting from the city center, which was named Andrássy Avenue (and it still is:). But they didn’t wanted to have fixed ground transportation (trams), that’s where the idea of the underground came from. The construction was finished in 1896, in the year of the Millenium of the Hungarian State. Out of the 11 stations 8 are reconstructed in their original state and 3 are new, since they have been added to the line in the 1970’s and 80’s. You can change to it from the other two metro lines in the center (Deák Tér), and you can get to Vorosmarty square, Hosok Square (Millenium Memorial), to the Opera House and so on. It’s also worth to see the exposition at every station!
