We provide arguments and evidences for the development of an environment for culture and art. We have prepared an umbrella document Cultural Policy of the City of Prague 22+, which defines the long-term vision, priorities and goals of the capital in the field of culture, art and cultural and creative sectors. Our project MAPK – Prague Culture Map collects data on cultural and creative sectors and other areas of cultural events in Prague. The collected data will allow us to analyze and find solutions or recommendations for the long-term development of culture in the city. We are also engaged in the evaluation of established programs, organizations and projects. Our project EVALUART serves to strengthen the work with data and concepts of Prague's cultural contribution organizations.
