Bucharest, in southern Romania, is the country's capital and commercial center. Its most iconic structure is the massive, communist-era Palatul Parlamentului government building, which has 1,100 rooms. Nearby, the historic Lipscani district is home to an energetic nightlife scene as well as tiny Eastern Orthodox Stavropoleos Church and 15th-century Curtea Veche palace, where Prince Vlad III (“The Impaler”) once ruled.
