The most complete charcoal-fuelled ironworks in Britain, Bonawe was founded in 1753 by Cumbrian iron masters who were attracted by the industrial potential of Argyll’s woodlands. Bonawe Iron Furnace is situated in a spectacular setting at the head of Loch Etive which extends up towards the dramatic Glen Coe.
At its height the furnace produced up to 700 tons of pig iron from Cumbrian ore annually which was cast into everything from cannonballs during the Napoleonic War to iron pigs for export and even the first monument erected to Admiral Nelson after the Battle of Trafalgar in 1805.
A detailed and informative exhibition charts the development of the furnace up until its closure in 1876 and explains the chemistry behind iron making. Today visitors can see inside the charcoal sheds – immense, cathedral-like structures – and admire the remarkably complete furnace.
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.
