THE "MUSEU DE LLEIDA: DIOCESÀ I COMARCAL" (Museum of Lleida: of the diocese and county) is an institution created by means of an agreement signed on the 1st of August 1997 in the form of an institutional consortium, made up of the regional government of Catalonia (the Generalitat de Catalunya), the provincial government (Diputació) and Lleida City Council, the County Council of Segrià and the Diocese of Lleida. The archives of the old Diocesan Museum of Lleida have been integrated into this Museum, created in 1893 thanks to the mammoth task of conserving our artistic heritage carried out by Bishop Josep Messeguer.
The Museum of Lleida opened its doors on the 24th of December of the same year with the exhibition Prooemium at the Romanesque church of Sant Martí in Lleida. It currently manages the diocesan collection , with important artistic pieces from the area of Lleida and the old diocese of Lleida. The new centre for the museum, which will be installed in the old Llar de Sant Josep, will include the archive from the archaeological collection and the Numismatic Office of the Institute of Lleida Studies of the provincial government, as well as the archive of the artistic collection of the New Cathedral of Lleida.
