A concrete retaining wall and roadbed had been erected next to a 16th century Safavid bridge to provide access to a factory; this project demolished the concrete structures to again unite the two sides of the site in the creation of a public plaza. The concrete was recycled to create foundations for new paving, steps, and public areas, and all of the new elements were crafted from local stone: grey marble for the terraced steps and red travertine for paving. Nearly all of the vegetation had disappeared, and great care was taken to nourish and maintain those trees that could be saved, and to plant drought-resistant grasses and shrubs in other areas.
