Mingarry Castle was considered a strategically important site in terms of communication with overseas areas and as an entranceway to the Sound of Mull. Originally built in the 13th century for the Clan MacDonald of Ardnamurchan, the castle has had many different occupants. King James IV of Scotland used it as a stronghold for fighting off Clan Donald in the late 15th century. In 1515 the castle was besieged by the Clan MacDonald of Lochalsh and again two years later when they finally took the castle.
In 1588 the chief of the Clan MacLean of Duart resided there after capturing the chief of the Clan MacIan of Ardnamurchan. In 1588, one of the ships of the Spanish Armada, named the San Juan de Sicilia, landed on Mull and MacLean of Duart used troops from the ship to aid him in his warring against the MacDonalds of Clanranald and the MacIans of Ardnamurchan. On one occasion, a force from the ship besieged to the castle for three days before withdrawing.
Other occupants over the years included the Clan Campbell, the Earls of Argyll (in 1612), and Alasdair Colkitto MacDonald who fought the English Parliamentarians of Oliver Cromwell in 1644. The majority of the current building dates from the 17th century onwards. Mingarry is roughly hexagonal in shape with nine-foot-thick walls, thicker on the seaward side.
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.
