Selected Legal Regulations and Cultural Aspects of Urban Development. Nowadays, the issue of urban development belongs to key elements of development in general. Urban development is a multifaceted phenomenon (covering economic, social, administrative, promotional, ecological and a number of other aspects). They are too numerous to discuss them in one short article. For this reason this paper is dedicated only to the phenomena regulated by law: physical planning, suburbanization (initially called urban sprawl), monument conservation and – additionally – culture (as a factor influencing the legal regulations). The key hypothesis is that developers are not the only ones to blame for the way the country looks. This hypothesis has generally been corroborated.
