When in Budapest, look up.
Budapest's buildings are beautiful and ugly, a fascinating mixture of all kinds.of architectural styles: gothic, classic, art nouveau, brutalist.
The uglier buildings are monumentally so, and tell of a dark history.
I went on a communist tour to discover some of the sights. The guide Andrew mentioned that during the communist times, the city was grey. Buidlings were neglected, allowed to accumulate layers of pollution and urban grime.
When the 1990s came and the ending of the communist era, the sense of optimism for the future must have been matched by a sense of joy at seeing buildings like these shine again.
