Bucharest has been Romania's capital city since 1862, and is a lively centre for Romanian art, architecture and culture. The city centre once boasted some of the most impressive architecture in eastern Europe, much of which remains throughout the city's historic old town. The city transformed under communist rule during the 20th century, and today displays a wide range of communist and modern architecture. Perhaps the best example of this is the colossal Parliamentary Palace, one of the largest government buildings in the world. The centre of this beautiful city is a lively mix of cafes, parks, and vibrant nightlife, punctuated with historic churches and excellent museums. Visitors here can wander the cobbled streets of the Lipscani district and take in the laid-back atmosphere from the many coffee shops and bars, or learn about Romania's long and interesting history at the city's world class museums.
