Tomba dei giganti di Li Lolghi is a burial chamber which probably dates back to the period included between 1800-1200 BCE. Like the tomb of Coddu Vecchiu, it was built in two different phases for different uses: during the Nuragic Age the original Dolmen, high a bit less than 4m and probably belonging to the Bonannaro's culture, was linked to a 10m corridor made up by stones stuck in the ground vertically. This new passageway was the new burial chamber where the dead used to be put in through a small entrance at the bottom of the Dolmen.
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.
