 In 1814 the parishes of Solothurn, in 1828 those of the Bernese Jura, and in 1864 also that district of Berne on the left bank of the Aar were attached to the bishopric of Basle.In compensation, Pius VII assigned, in a papal brief of 20 September 1819, the city of Geneva and twenty parishes belonging to the old Diocese of Geneva (which in 1815 had become Swiss) to the See of Lausanne.The bishop (in 1815 Petrus Tohias Yenni) retained his residence at Fribourg, and since 1821 has borne the title and arms of the Bishops of Lausanne and Geneva.
