The project “Tgarden Visitors’ Centre is planning to contribute to increasing Brownfield location in the City of Osijek for public and economic purposes, through the reconstruction of the construction, the building of supporting infrastructure and the environmental architecture of the Hornwerk area. The project covers the renovation of buildings, road construction and car parks, as well as landscape amenities. The need to implement the Project stems from the need to revitalise the left (military) area, to improve the management of the protected cultural historical unit of Osijek, but also to establish a regional reception centre, which is missing in the tender, and in order to provide the basic service standards for the city and region.
