The Cathedral of St. John the Baptist in Albacete is a Catholic church with Mudéjar origins (13th century) and Renaissance construction (begun in 1515), completed in 1949 in Neo-Romanesque and Neo-Gothic styles. It is a Site of Cultural Interest, an episcopal seat, and houses the image of Our Lady of Los Llanos.
The biblical paintings by Casimiro Escribá are particularly noteworthy, considered one of the greatest pictorial works in the world.
