San Marcos is a Gothic church in Jerez de la Frontera. It originates from one of the six parishes founded by King Alfonso X of Castile after his conquest of the city in 1264. The current edifice was likely started in the mid-14th century, due to the style of its polygonal apse and the Mudéjar portal, perhaps above a pre-existing mosque. The construction is anyway not documented until the middle of the 15th century, including a substantial renovation in late Gothic style.
The church has three façades, with a main entrance portal in Mannerist style (16th century). The interior has a Baroque high altar (18th century)References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
