Agno () is a historic town and a municipality in the district of Lugano in the canton of Ticino in Switzerland. Due to its position on Lake Lugano it is popular with tourists, and hosts summer festivals, with two hotels and several camping grounds. It is served by the Lugano-Agno airport. The official language of Agno is Italian. History Agno is first mentioned in 818 as Anium. It was known by its German name Eng, though this is no longer used. Pieve of Agno The emergence of the Pieve or Parish of Agno is related to the spread of Christianity in late-Roman era along the Milan-Como-Riva San Vitale axis. The dedication of the church to Saint John the Baptist (San Giovanni Battista) refers to its character as a baptistery. Documents from the years 735 and 818 (deed of gift by King Louis the Pious) testify to the existence of a religious center at Agno.
