In Yerevan, as well as in a number of other Armenian cities, gardens were designed and constructed mainly during the Soviet era, and most of them were transformed, distorted and devastated in the first decade of the period of independence. In the last decade, a unique number of gardens/parks have been built or reconstructed in Yerevan. The city of Yerevan needs this kind of investigation. To observe and analyse the current state of gardens and parks, architectural and design structures as well as compositional design issues and problems concerning Yerevan’s gardens and parks can be the first study in the Armenian history of design and architecture We still do not have any information about similar research efforts in the given sphere carried out in the countries neighbouring Armenia and other foreign countries. This article presents the right process of modernization and/or construction of gardens/parks based on the study of the best models envisions and requires application and implementation of different tools of compositional design and modification not only in the design proper of gardens/parks, but also in the external design and aesthetic nuances of the adjacent surrounding, leaving any compositional design setup unchanged.
