In the Czech Republic, but elsewhere in the world, there are areas, buildings or complexes that have lost their previous use and have been dilapidated or used little. This diploma thesis aims to map out how big brownfield problems are in individual regions of the Czech Republic and whether the regions themselves help to solve this unsatisfactory situation. The partial objective was to evaluate the use of available financial resources provided by the European Union in the 2007-2013 programming period for projects related to brownfield regeneration in the Czech Republic.
