In this thesis, taking into account all the demands of tendered urbanistic–architectural contest and spatial problems, trough analysis and inventories, possibilities of landscape design of Perivoj on bastion Citadel were examined. Taking in the consideration cultural and historical value of Zadar parks and walls it was important to explore their history, their interconnection and especially development trough time periods and changes in the park. Those revelations were the key for proposing a new design. It was important not to deny the history of the park that is to follow conservation guidelines, and to balance between the visual appeal of this space and the demands of the Zadar City. From that starting point three mutually different concepts with different philosophies were developed. All three concepts where created for the purpose of achieving the residential, theatrical, aesthetical and functional space from which the most attractive one was chosen for the final design scheme. The final landscape concept design includes green surfaces, the designed theatrical space, balanced contents for outdoor living and socializing, communication paths within the park with open view towards the sea and also provides access for people with special needs. This has created an attractive place with social character for all the residents of all ages, as well as tourists and other visitors.
