Residing over Plaza del Mercado Grande, San Pedro projection is similar to that of the Basilica of San Vicente. The monarchs swore their respect for the charters of Castile in the atrium of the church, which underlines its importance during the period in which the town achieved its greatest relevance in the world of politics.
San Pedro has a Latin-cross layout with a central nave that is larger than the side naves. Its construction began in the second quarter of the 12th century and was completed in the 13th century after a period in which the work was stopped. The architecture and decoration shows an evolution of particular interest as a result of the delays in the construction work.
It has a triple upper end with an apse on each nave and a magnificent collection of sculptures showing plant, animal and geometric motifs and scenes from the Bible. The ceilings were covered with barrel and groined vaults in the 13th century. Over time, the arches became forerunners to those used in the Gothic period. Finally, a tower was built on the place where the central nave intersects with the transept.
The main front has two bodies: the upper body is dominated by a large rose window and the lower body has a porch in which the size of the entrance is magnified by six plain archivolts. The southern porch is similar but smaller in size. The northern entrance is more ornamental and moulded with five archivolts, two of which are decorated with typical Ávila-style rosettes.The interior stands out thanks to the panels distributed around the walls of the nave, the Renaissance-style altars and the altarpiece in the main chapel, together with its grilles.It was designated a National Monument in 1914.
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.
