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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
