The Scord of Brouster is one of the earliest Neolithic farm sites in Shetland. It has been dated to 2220 BC with a time window of 80 years on either side. It comprises three houses, several fields surrounded by walls, and a cairn. A sign by the Scord of Brouster states that the climate of Shetland became wetter towards 1500 BC, and that peat forming near the fields eventually forced the farmers to permanently abandon the site. The Scord of Brouster has three oval-shaped houses.
In all, nearly ten thousand pieces of quartz were found at the Scord of Brouster. 5688 stone artifacts were found in house one, 3772 stone artifacts were found in house two, and only 227 stone artifacts were found in house three. Of the 227 items found in house three, 225 are merely quartz flakes and chips. These pieces were found in what appears to be three phases: prior to the construction of the buildings, during active use, and during abandonment.
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.
