The analysis of provisions of Local Spatial Management Plans and selected cases of practical implementation of such provisions showed, that the provisions of spatial law practically stay without any relation to rules of urban composition and spatial order. The research was limited to analysis of urban composition, without considering all the conditions for planning process and its results. The town planning is treated in this article as planned space resulted from clear urban concept based on general urban composition rules. Town planning does not refer in this case to spatial chaos which can be a result of implementation of Local Spatial Management Plan.
The metropolis of Barcelona is one of the first ten Europe's urban agglomerations. The geographic and natural conditions of the city - located in area between the sea and the forested mountain ranges running parallel to the coast and divided by broad river valleys - have considerably influenced the formation of its hybrid urban structure. The heart of the agglomeration is still Barcelona, established by the Phoenicians in a natural port at the foot of the Montjiuc hill, growing together with its neighbouring towns for more than two thousand years now, incessantly filling one fragment of natural landscape after another with urban fabric. Monumental edifices and high-rise buildings erected in all historic periods have been inorming visitors of the power of teh city and the same time defining places which are important for its urban composition and status. Recent decades have brought no revolutionary changes in this trend. What was changed, though, are the architectural forms of those most emblematic structures in the scale of the metropolis.
