The former Italian Catholic Diocese of Chiusi-Pienza, in Tuscany, existed until 1986. In that year it was united into the Diocese of Montepulciano-Chiusi-Pienza. The Diocese of Chiusi (Clusinus) was at first immediately subject to the Holy See, but was made a suffragan of archdiocese of Siena by Pope Pius II.[1] From 1459 to 1986, it was a suffragan of the archdiocese of Siena.[2][3]
