Is the architecture of Buenos Aires still dominated by Spanish colonial styles?

[Yoodle15]

If not, what type of architecture dominates today?

[poli]

It has very little in the form of Spanish colonial architecture in Buenos Aires. There is a notable Belle Epoch presence throughout the city. In 1940 Buenos Aires must have been a truly beautiful place. Unfortunately there was a building boom in the mid-20th century which is, at best, nondiscript. I'm afraid this poor architecture dominates. There is a small attractive 21st century building boom at the waterfront with quite a few skyscrapers.
