The Peel of Lumphanan is a defensive structure dating back to the 13th century. The peel comprises a mound or motte, surrounded by two concentric ditches separated by a bank. On the top of the mound are the remains of a wall, and the foundations of a house. The entrance was probably located to the west. The lower half of the motte consists of a natural mound; it was heightened when the castle was built.
A motte on this site is thought to have been in existence at the time of the Battle of Lumphanan. This battle was fought nearby in 1057, between King Macbeth and the future King Malcolm III. Macbeth was killed, and Macbeth's Stone, upon which he is said to have been beheaded, is located 300 metres to the south-west.
The present mound was constructed in the 13th century by the De Lundin family, who later adopted the name Durward from their hereditary position of royal ushers or door-wards. Sir John de Melville paid homage to Edward I of England at the peel in 1296. The original ramparts may have been of turf rather than stone. The rectangular foundation is that of Halton House, which was built in the 15th century by Thomas Charteris of Kinfauns. The circular wall, originally thought to have been the curtain wall of a shell keep, was discovered through excavation in the 1970s to be of 18th-century date.
The site is under the guardianship of Historic Scotland, and is protected as a scheduled monument. It is considered to be of national importance as 'a good surviving example of an earthwork castle with water-filled outer defences.'
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.
