The Palacio de la Merced is a historical building in Córdoba. Once home to the convent of La Merced Calzada, it is now home to the Provincial Government of Córdoba, a sovra-municipal services institution of the province of Córdoba.
Excavations in the site have revealed the presence of ancient Roman ashlars. Later findings include medieval remains of a baptistery and of a crypt, identified with the Palaeo-Christian or Visigothic basilica of St. Eulalia, assigned by some scholars to the reign of king Reccared I.
The foundation of the palace is traditionally connected to Peter Nolasco, whom king Ferdinand III of Castile had donated the Basilica of St. Eulalia after the conquest of the city in the early 13th century. There are few traces of the 13th convent, however. The current edifice dates to the 18th century, the church dating to 1716-1745. The later has a Latin cross plan, with a nave, two aisles and a transept. The cloister, with a rectangular plan and round arches, was finished in 1752.
Some renovations occurred in 1850, when it became a hospital, and 1960, when it became the seat of the Provincial Deputy. In 1978 the church suffered a fire that destroyed the high altar and other artworks.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
