However, after 1200 BC there is very little evidence for further Bronze Age settlements in the canton. Only eight Iron Age sites have been discovered in the canton from the 8th to 1st centuries BC. During the Roman era a Roman Vicus was established at Kempraten in Rapperswil around the massive bridge at Seedamm (near the Bronze Age bridges) which crossed into Schwyz. A Gallo-Roman temple was built on Ufenau island around AD 200 on the site of the present chapel of Sts. Peter and Paul. A few Roman coin hoards were discovered at Küssnacht and Rickenbach bei Schwyz and Küssnacht may have been the site of a Roman estate.
