Plasencia's cathedral was founded in 1189 and rebuilt after 1320 in an austere Gothic style that looks a bit incongruous looming over the town's red-tile roofs. In 1498 the great architect Enrique Egas designed a new structure, intending to complement or even overshadow the original, but despite the later efforts of other notable architects of the time, such as Juan de Alava and Francisco de Colonia, his plans were never fully realized. The entrance to this incomplete, curious, and not wholly satisfactory addition is through a door on the cathedral's ornate but somber north facade. The dark interior of the new cathedral is notable for the beauty of its pilasters, which sprout like trees into the ribs of the vaulting. You enter the old cathedral through the Gothic cloister, which has four enormous lemon trees. Off the cloister stands the building's oldest surviving section, a 13th-century chapter house, now the chapel of San Pablo, a late-Romanesque structure with an idiosyncratic, Moorish-inspired dome. Inside are medieval hymnals and a 13th-century gilded wood sculpture of the Virgen del Perdón. The museum in the truncated nave of the old cathedral has ecclesiastical and archaeological antiques.
