Narberth Castle is a ruined Norman fortress in the town of Narberth. The current ruins are undoubtedly Norman and seem to date from the 13th century, having been built by Andrew Perrot. However the castle is mentioned in the third branch of the Mabinogi as the place where Rhiannon was imprisoned and forced to carry travellers through the gates as penance for killing her son. Although there is some controversy over the actual location of the castle in the Mabinogi (there are at least two other earthworks nearby that are contenders, but neither are in good defensive positions compared to the site of this one), the Normans often built castles on top of earlier defensive structures and it is plausible that the original was obliterated.
The castle never changed hands throughout the Glyndŵr Rising in 1400–1415 and was slighted after being taken by Oliver Cromwell in the English Civil War. Excavations have found more than 20 graves on the north side dating from the 12th century to the 13th, hinting that the area may have once been the site of a church.
In the early part of the 20th century, the annual town fair held a procession which ended in the castle, with dancing and music. In 2005, the castle was opened again to the public after being taken over by the council and made safe.
The castle has provided a good deal of building material for the surrounding houses and the remains are mostly single and double storey walls, with the barrel-vaulted kitchen cellars intact. No upper storey rooms are intact. There is an early engraving visible on an information board at Narberth railway station (and possible elsewhere in the town) which shows now-vanished tall chimneys of a Flemish style that can still be seen at the well-preserved Manorbier Castle.
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.
