Lanzada is an archaeological site is composed of a castro (hillfort settlement), a necropolis, a medieval fortification and a chapel. A bronze socketed axe with two loops was found in the vicinity of the town of A Lanzada and is now housed in the National Archaeological Museum. Three more axes were uncovered in another part of the site, two of which belonged to the Marquis of Riestra and one that he gifted to an English subject. In the summer of 1969, a bronze Irish-style sickle was found among the remains of a landslide in the Norte del Castro area near the chapel.
Excavations revealed the existence of a castro settlement and a large late Roman necropolis with cremation and inhumation tombs. Bone and bronze pins, coins, shoe nails, and tegulae or flagstone graves were also recovered. The settlement and the necropolis are on both sides of the road. In 1969 and 1972 a stratigraphic analysis confirmed the existence of the settlement and its occupation from the late Bronze Era to the last stages of the Romanisation process, which makes it very significant.
Lastly, there is a Roman stela on the south side of a path known as A Ponte, which connects the mainland to the isle where the chapel is located. Fragments of castro pottery were found on the isle.

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.
