Llanthony Priory s a partly ruined former Augustinian priory. The priory dates back to around the year 1100, when Norman nobleman Walter de Lacy reputedly came upon a ruined chapel of St. David in this location, and was inspired to devote himself to solitary prayer and study. A church was built on the site, dedicated to St John the Baptist, and consecrated in 1108. By 1118, a group of around 40 monks from England founded there a priory of Canons Regular, the first in Wales.
In 1135, after persistent attacks from the local Welsh population, the monks retreated to Gloucester where they founded a secondary cell, Llanthony Secunda. However, around 1186 another member of the de Lacy family, Hugh, the fifth baron, endowed the estate with funds from his Irish estates to rebuild the priory church, and this work was completed by 1217.
The Priory became one of the great medieval buildings in Wales, in a mixture of Norman and Gothic architectural styles. Renewed building took place around 1325, with a new gatehouse.
Following Owain Glyndŵr's rebellion in the early 15th century, the Priory seems to have been barely functioning. In 1481 it was formally merged with its daughter cell in Gloucester, and after 1538 both houses were suppressed by Henry VIII's Dissolution of the Monasteries.
The buildings at Llanthony gradually decayed after the Dissolution to a ruin, although in the early 18th century the medieval infirmary was converted to the Church of St David. In 1799 the estate was bought by Colonel Sir Mark Wood, the owner of Piercefield House near Chepstow, who converted some of the buildings into a domestic house and shooting box.
The ruins have attracted artists over the years, including J. M. W. Turner who painted them from the opposite hillside. Wood's house later became the Abbey Hotel. The remaining ruins are protected by Cadw and entrance to the ruins is free.
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.
