Āgenskalna Priedes or Pine-trees of Āgenskalns is the first large-scale residential district in Riga. It was built in two stages between 1958 and 1962. It was the time marked by radical changes in architectural style, mass-building technology and urban planning: “socialist realism” prevailing in the Soviet realm was replaced with a simple and rational style in architecture that to some extent may be compared to Modern Movement, assembly of large prefabricated concrete elements replaced traditional construction methods and construction became more extensive covering larger territories with standard buildings. Thus, this district became a herald of a whole new era in architecture and urban planning.
