Wiston Castle is a motte and bailey castle in the Pembrokeshire village of Wiston. The castle and village were founded by Wizo, a Flemish settler who was granted the land by Henry I of England after he had wrested control from the previous owner, Arnulf de Montgomery (who was in revolt against Henry). The castle was captured by the Welsh on several occasions but on each occasion it was retaken. It was abandoned during the thirteenth century when the then owner moved to nearby Picton Castle.
Wiston Castle is considered one of the best preserved motte-and-bailey castles in Wales. It is built on the summit of a hill to the north of Wiston with the motte about 9 m above the base of the ditch. Surrounding the flat top there is a shell-keep that would have been the main fortification inside which all the buildings, mostly made of timber, would have been placed. The external face of the shell-keep is polygonal, with eighteen short sections, but some of these have subsided into the ditch on the north side. The inside of the shell-keep is circular. There is an arched entrance on the south side and on either side of this there are draw-bar holes which would have been used to secure the main gate. Inside is a large, oval bailey protected by a well-preserved bank. The lord's main residence would have been inside the bailey.
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.
