The project regards the extension of archaeological paths, inserted into the landscape, and urban history of the Roman Iulia Concordia.The project aims at enhancing the heritage of the Roman city and the understanding of the significant elements of the ancient structure for the visitors. All elements of the composition, from the paths to the vegetation, are designed to visually communicate the progress of the ancient system, in particular the ancient walls and canals. A link with the past is created by the planting of plants species used in Roman times, as laurel, boxwood, oak, iris and lavender. Significant points are marked by the planting of trees of great growth and long life, the English oak (Quercus robur), as in the Thermae. The linear development of the paths is marked by a single species climbing pillars and wire mesh. The hypothetical extension of the theater and its walls is indicated by a sign of lavender (Lavandula angustifolia 'Alba'), while the area of the orchestra offers a paving of gravel referring to the material used in Roman times. The laurel (Laurus nobilis) forms a hedge along the archaeological path west of the walls, as a screen towards a messy existing urban context. The iris (Iris sibirica) in a slight depression in the park evokes through its blue flowers in spring, the presence of the canal that ran here in Roman times.The iris (Iris sibirica), planted in an area where the ground is lower, evokes thanks to its blue flowers in the spring the presence of the canal that was running here in Roman times.
