Maeshowe is a Neolithic chambered cairn and passage grave. It was probably built around 2800 BCE. It gives its name to the Maeshowe type of chambered cairn, which is limited to Orkney. Maeshowe is a significant example of Neolithic craftsmanship. The monuments around Maeshowe, including Skara Brae, were designated a UNESCO World Heritage Site in 1999.
Maeshowe is one of the largest tombs in Orkney; the mound encasing the tomb is 35m in diameter and rises to a height of 7,3m. Surrounding the mound, at a distance of 15m to 21m is a ditch up to 14m wide. The grass mound hides a complex of passages and chambers built of carefully crafted slabs of flagstone weighing up to 30 tons. It is aligned so that the rear wall of its central chamber held up by a bracketed wall, is illuminated on the winter solstice. A similar display occurs in Newgrange.
Estimates of the amount of effort required to build Maeshowe vary; a commonly suggested number is 39,000 man-hours, although Colin Renfrew calculated that at least 100,000 hours would be required. Dating of the construction of Maeshowe is difficult but dates derived from burials in similar tombs cluster around 3000 BC. Since Maeshowe is the largest and most sophisticated example of the Maeshowe 'type' of tomb, archaeologists have suggested that it is the last of its class, built around 2800 BC. The people who built Maeshowe were users of grooved ware, a distinctive type of pottery that spread throughout the British Isles from about 3000 BC.
A Neolithic 'low road' connects Maeshowe with the magnificently preserved village of Skara Brae, passing near the Standing Stones of Stenness and the Ring of Brodgar. Low roads connect Neolithic ceremonial sites throughout Britain. Some archeologists believe that Maeshowe was originally surrounded by a large stone circle. The complex including Maeshowe, the Ring of Brodgar, the Standing Stones of Stenness, Skara Brae, as well as other tombs and standing stones represents a concentration of Neolithic sites that is rivalled in Britain only by the complexes associated with Stonehenge and Avebury.
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.
