The palatial Late Antique Roman villa at La Olmeda was built in several stages, beginning in the second quarter of the fourth century and extending in use at least to the end of the fifth. The villa complex centers on the elite quarters of rigorously symmetrical disposition, wherein twenty-seven rooms, twelve with mosaic floors, are disposed around a central patio crossed with mosaic paths in geometric patterns and linked round its perimeter by a wide peristyle. This main building housed the poentior, with its oecus or reception hall, centered in the east wing featuring a particularly resplendently mosaiced floor. Slightly raised semicircular apses mark its northeastern and northwestern end rooms.
The main body of the villa communicated with a baths by a grand passageway. The principal front of the main block faces south, with a porticoed gallery ending in octagonal tower blocks. The residential quarters face north with two rectangular corner towers.
The complex also included working and living quarters of more rustic aspect, kilns for baking roof tiles on the site, three burial grounds, and a section of paved roadway.
Today the site open to the public, while a museum dedicated to the finds is housed in the nearby church of San Pedro de Saldaña.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
