The original Dunimarle Castle is now a ruin, but adjacent to it stands an 18th-century building, borrowing its name, constructed by the Erskine family. The house was rebuilt by R & R Dickson in 1839. It has a good library. Until recently it had some fine art which is now found on temporary loan to the National Galleries museum at Duff House, near Banff, North East Scotland.
From 1575, Dunimarle Castle had a coal mine in operation run by Sir George Bruce. The mine had a tunnel that led down to the nearby River Forth, which is some 30 meters below, this was so that the coal could be loaded onto ships. The mine was abandoned in the early 17th century and the tunnel filled in.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.
