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 Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
