In Kraków and Katowice will arise two huge congress centres offering 40 000 sqm of space, respectively at the price of 360 mln and 303 mln złotych. The costs will be partly covered from the grants awarded by the European Union. In Kielce and Opole will arise two smaller congress centres, intended for the same purposes. The investments are meant to meet the needs of business tourism, which actually represents about 25% of foreigners arrivals.
