Rona, a remote Scottish island, is said to have been the residence of Saint Ronan, Abbot of Kingarth in Bute (died 737). A tiny early Christian oratory which may be as early as this date, built of unmortared stone, survives virtually complete on the island. The site of one of the most complete Early Celtic religious complexes in Scotland. North Rona was abandoned after the Viking raids, but resettled by a secular community in the 12th or 13th century. Disasters, such as the drowning of the island's entire male population, and starvation brought about by a plague of rats, resulted in only intermittent occupation during subsequent centuries; the last resident, Donald Macleod, left in 1844 . North Rona is now a National Nature Reserve with Sula Sgeir.
Sited on a terrace within a thick-walled, oval burial enclosure, Teampall Rònain was probably a hermitage offshoot from the church at Europie in Lewis. It is two-chambered, the almost subterranean corbelled eastern cell being the late 7th/early 8th century `oratory' of St. Ronan, beautifully constructed with inward-leaning walls bridged over with stone slabs, traces of lime mortar still clinging to the sides. On the west wall, a door with slit window above leads into the 12 th-century chapel, its west gable still standing to six or seven ft. A stone-paved doorway was uncovered by Dr. Frank Fraser Darling on the south wall during his repair works here in 1938. He also excavated the east end of the earlier structure, unearthing the base of a stone altar and wall niche. Numerous Early Christian and medieval incised cross slabs lie on the site.
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.
