The Torelló settlement was one of the largest in the municipal area of Mahón. It is especially well known for the spectacular talaiot (called the Talayot of Torellonet Vell) which is interesting because at the top of the tower you can still see the original doorway and the lintel above it, both of which date from the Talayotic period (1000-700 BCE).
Unfortunately, the structure was damaged by the triangulation pillar and the airport-runway approach lights that were placed on the tower platform. An archaeological dig carried out on the site in the 1980s unearthed lamps dating from the period of Imperial Rome plus the remains of fine Roman pottery.Of all the structures identified in the settlement, the most interesting are a second talayot (much smaller in size); the foundations of several houses; a couple of artificial caves; plus a water catchment system made up tanks or cisterns and channels.
References: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.
