Brecon Castle was built by the Norman Lord Bernard de Neufmarché in 1093, and was frequently assaulted by the Welsh in 13th and 15th centuries. The castle's ownership changed numerous times. It began falling into ruin when Henry VIII executed the last dukes of Buckingham, who at the time controlled the castle. It was renovated and made into a hotel in the early 19th century.
Numerous renovations were carried out through the castle's history. A shell keep made of stone was constructed in the late 12th century (the keep was initially made of wood). In 1233, a bailey wall, also made of stone, was constructed. Two towers, one round and the other semi-octagonal, were built in the 13th century and early 14th century, respectively. A hall block was added in 1300.
The castle had become mere ruins by the end of the Georgian era. Renovations were begun in 1809 by Sir Charles Morgan of Tredegar House, and more than £7,000 had been spent on the repairs by 1814. The castle was made a hotel, which it currently continues to be.
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.
