Two of the most extravagant Art Nouveau/Secessionist buildings in Budapest are within easy walking distance of City Park. To the southeast is Sándor Baumgarten’s National Institute for the Blind , dating from 1904, and to the south is the Institute of Geology , designed by Ödön Lechner in 1899 and probably his best-preserved work. Check out the three figures bent under the weight of a globe atop the stunning blue Zsolnay-tiled roof.
