Warsaw is the capital and the largest city of Poland. Unlike most Polish cities, Warsaw's cityscape is mostly contemporary – modern buildings are towering above older historical edifices. The buildings in the Warsaw Old Town represent nearly every European architectural style and historical period.
Katowice is a large business, conference and trade fair center. Unlike most other large Polish cities, Katowice did not originate as a medieval town. Katowice's urban layout is a result of expansion and annexation of various towns, industrial worker estates, and villages.
