Despite the fact that Poland was flattened in WWII, an impressive amount of historic beauty remains, and many of the towns and cities that were destroyed in the war have painstakingly rebuilt their historic cores. This is particularly true of the capital, Warsaw, which lost some 90 percent of its building stock in the war, but which now boasts an 'Old Town' that while a scant four decades in age looks every bit as impressive as it did four centuries ago. Many of the oldest Polish cities got their start in the 13th and 14th centuries, when Gothic architecture was all the rage. They grew wealthier in the subsequent centuries, adding impressive Renaissance and Baroque facades to their town squares. You're never far from a castle or cathedral (usually both), which lend a regal element to the medieval cityscapes.
