Archaeological Site of Lastra Place at Montegrotto Terme: the area where nowadays the Hotels Vulcania and Bagno Romano stand, south-west of Colle San Pietro Montagnon or Montagnone, owes its name – “Lastra” – to the continuous emerging of ancient marble slabs during the 18th century. Two thermal pools with ducts and some Roman buildings with mosaic floor (approximately 1st century B.C. – 1st century A.D.) also emerged in the 19th century, as well as some votive objects datable around 7th – 6th century B.C. – similar to the finds discovered at the sacred place between Monte Castello and Colle San Pietro Montagnon. Information about the emerging of marble slabs and the presence of thermal water sources was reported by Salvatore Mandruzzato, author of the treatise “De’ bagni di Abano” (written between 1789 and 1804). The buildings with mosaic floor were discovered by the “Commissione Austriaca per i monumenti antichi della zona termale” on 27th July 1827, within the Moisé Trieste ownership; the pools and the proto-historical finds were discovered in November 1863, within the Sette ownership. The 19th-century drawings concerning these structures are currently preserved at the Biblioteca Civica di Padova.
