Since Roman times, baths have served as important social and meeting places. The Roman Baths at the base of the Serail hill exhibits such features as brick vaults supporting the floors and allowing the air to circulate, heating the warm and hot rooms and bathing areas. After undergoing excavation and clearance, the site was restored and landscaped. A terraced garden designed with a cascading fountain is typically planted with pine and olive trees; aromatic herbs such as oregano, basil and thyme; and scented flowers such as violets, jasmine and lavender. A pedestrian open space and a small amphitheater host open-air plays and concerts. The Roman Baths gardens, pedestrian open space and stairs allow access to the Grand Serail.
