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.
The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
