The proposed intervention begins with the arrangement of the moat as in the historical profile. The trough is filled with water, hydrologically controlled and connected to the Sava River. An imprint of the building elements of the historical matrix is formed around the canal. Green embankments, voluminous green forms that interpret linnets, ravelins, counterguards, redoubts and archaeological points at the location of preserved fragments will be built. Next to the relief formed in this way, a promenade is laid around the moat’s outer profile – a bicycle lane that follows the old and new structures in a historical theme and connects it with the route of the path along the Sava Embankment. The path literally follows the historical matrix, so at the point where the contour of the fortress is interrupted by the city road, it becomes a bridge – an overpass over the street of the city of Vukovar.

A backdrop in the form of a botanical garden is proposed on the northern edge of the preserved and present historical structure. The premise of the intervention is to highlight the essence of the existing with a landscape collage, while functionally designing the whole with a modern but neutral approach. The central zone of the botanical garden literally interprets the imprint of the historical “star-shaped” design with emphasized lines of communication that divide and connect the green space. The fabric of the garden is formed in a crystalline grid of trapezoidal fields in a functionally organized structure of vibrant concentration of content. Different thematic niches, green rooms were designed; such as a wet garden, a lake garden, a herb garden, an iris garden, a fern garden and various thematic plant collections. The imprint of the star was additionally interpreted by the reconstruction of the historical row of trees on the western side. To the north and west of this controlled enclosure is the area of the arboretum (botanical collection of trees) which is softly interwoven with organic paths, in a landscape manner. The arboretum zone discreetly and softly connects with the green surface of the marginal green zones. Towards the western border, a compact green buffer would be formed as visual and sound insulation, which would also represent a passe-partout against the voluminous, green formations on the clean lawn. The dominant greenery would be from the Posavina area. It would undoubtedly determine the location and authenticity of the cultural and natural landscape.

On the other hand, the building of the botanical garden will mark the entrance to the garden, a building structure located on top of the former asphalt or concrete surface. The building in the aerial view represents the green integral area of the botanical garden. The current road, parking area becomes a roof area surrounded by greenery, integrated into the ground floor solution, and a transparent, crystalline, at first glance irregular form penetrates through it. The entire composition of the botanical garden is built on the basis of the former contours of the fortress. While the garden follows the arms of the historical “star-shaped” design, the complex approach of the building preserves the perimeter of the parking lot in the form of a neutral green area into which the former “Linnet number X” is pressed. Thus, the glass building follows the “Linnet” line, with a row of trees following the same path on the otter façade, and the negative space that was left within the Linnet X as the new square.
