Santa Marina is one of the so-called 'Fernandinean Churches', edificated in the city after Ferdinand III of Castile conquered it from the Moors in the 13th century. The structure combines proto-Gothic, Mudéjar and, to a lesser degree, late-Romanesque elements.
The church, one of the oldest of the Fernandinean group, was built in the second half of the 13th century where previously a Moorish mosque and before that a 7th-century Visigothic church had existed. No trace of them remains today.
On 23 June 1880 the church suffered a fire, which required a restoration lasting two years. Other renovations were carried out in the 19th and 20th centuries, during which the medieval appearance of the building was restored, by removing the Baroque additions introduced after the damage from the 1680 and 1755 earthquakes.
The church has a rectangular, or basilica, plan, divided into a nave and two aisles, the nave being far higher than the latter. The aisles are separated from the nave by large pointed arches.
The facade is characterized by four large, asymmetrical buttresses, ending with pinnacles, and corresponding to the interior separation between nave and aisles. Also present are a main central rose window, smaller circular windows, and alfizes over the ogival arch of the main portal. The facade corresponding to the left aisle features a secondary portal, surmounted by a triangular arch.
The apses are polygonal. In the right aisle is the sacristy, built in the 15th century. The left aisle apse was adapted to house a Baroque chapel from 1630. The bell tower dates to the 16th century.
The 'retablo' of the Main Chapel houses paintings by Antonio del Castillo and sculptures from the local artist Gómez de Sandoval.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
