Bucharest has been called "Little Paris", and for a few decades around 1900 it earned it: French architects, wide boulevards, a triumphal arch and an Athenaeum where the elite heard the best orchestras in Europe. Then came two world wars, an earthquake in 1977 and Nicolae Ceaușescu, who in the 1980s flattened some 7 square kilometers of the historic center south of the river, monasteries and churches included, to build a palace and a boulevard for a socialism that ended before either was finished. The city that's left is a collage, and that's what makes it interesting: a Byzantine church in the courtyard of a concrete block, a Belle Époque bank next to a 1970s department store.
It's also a capital that lives well. Romanians eat late and generously, the coffee is good, and the nightlife runs from beer halls with folk bands to techno clubs that people fly in for. Most visitors give it a day on the way to Transylvania. Five days is enough to see why locals defend it.
Day one is the Palace of the Parliament and the Old Town, day two Calea Victoriei and the square where 1989 happened, day three the north: the Peasant Museum, the Arch, the Village Museum and Ceaușescu's own house. Day four is a train into the mountains to Sinaia and Peleș Castle, and day five the markets, interwar Bucharest and a long soak at Therme.
