The natural environment of the Baltic Sea coast becomes the life habitat of the people who settled there. By changing the water and greenery systems and creating architectural structures a new, functional environment was established. Nature elements began to be included in the architectonic spatial structure of the cities. In the first half of the 19th century the first public gardens were established in the cities of the western region of Latvia. Several decades later, urbanization and transport development changed the urban environment, thus reducing the proportion of nature elements. The natural landscape was replaced by artificially designed green plantations—squares, boulevards and public parks became part of the amenities. At the time of Latvian Republic the agrarian reform—division of the state land fund, allocation of new land for urban construction, and alienation of manor properties—provided cities with an opportunity for planned development. After the restoration of Soviet power in 1940 Latvia was annexed by the Soviet Union. Nature transformation projects were environmentally imprudent and many urban areas were considered as a dimensionless trash bin. Greenery was arranged at completely new constructions of a different scale without previous practical experience, while low level of maintenance of green plantation had a negative impact on people's quality of life. After regaining independence and accessioning to the European Union, cities of western region of Latvia need to improve the architectonic spatial structure to maintain the proportion of green plantations. The open space created by nature elements, such as water basins and greenery system, will provide favorable conditions for the healthy living and an artistic touch to the urban environment.
