I recommend walking the two-kilometer Andrassy Avenue at least once while you're in Budapest. The avenue was built in the late nineteenth century and, as the surrounding area was just farmland, the buildings surrounding it also had to be built. The intention of Prime Minister Gyula Andrassy was to turn Budapest into a major metropolis to rival Vienna and he decided to build no only the avenue, but also the Opera House and Heroes' Square. After its construction, Budapest actually became one of the top cities in Europe. Given its length, the architecture along the Andrassy Avenue varies a bit. The beginning of the avenue which runs from the center until Oktogon is one of the richest and most glamorous parts of the city, a place where you'll find names like Dolce & Gabbana and Armani and where it's not uncommon to spot limos and Ferraris on the street.
