 Archaeologically excavated are the remains of public baths (Thermengasse), graves and traces of craft enterprises, residential buildings, as well as everyday objects and jewelry, but also of cult equipment.Archaeological excavations usually were executed on occasion of renewals of present buildings at Rennweg 5/7 (settlement structures), Fortunagasse 28/Rennweg 38 and Oetenbachgasse 5–9 (Celtic trench and settlement structures), Münzplatz (settlement structures), Lindenhof hill (Celtic, Roman and medieval settlement structures), Rennweg 35 (Celtic spot plates ("Tüpfelplatten") and settlement structures), the Limmat (bars) and Bürkliplatz-Bahnhofstrasse (Celtic Potin coins), all representing the Helvetii and early Roman settlement.Focussed on the Gallo-Roman era, archaeological explorations were executed at Weinplatz 3/4/5 and Storchengasse 23 (harbour area and thermae), Storchengasse 13 (cultic building) and neighbored Fortunagasse 28/Rennweg 38 (maybe a hostel) and gold jewellery at the Sihlbühl area, Poststrasse/Zentralhof at Münsterhof (probably early medieval graves), and the island sanctuary ("Rundtempel") on the former "Grosser Hafner" island.
