a town of Switzerland, in the canton of Bern. E. Long. 5. 54. N. Lat. 48. 30. It is situated near a river of the same name, seven miles north of the lake of Geneva, upon an eminence which has a gentle declivity, at the foot of which runs the river with an impetuous torrent. The town is built in the form of an amphitheatre; on the upper part of which stands a very handsome castle with a fine court, and a portico supported by pillars of a single stone each; above there is a covered gallery that runs round the court; and as the castle stands high, there is a most delightful prospect, not only of the town and neighbouring fields, but of the whole lake of Geneva and the land that surrounds it. At Thonon, in Savoy, on the other side of the lake, is a town covered with tin, which makes a glittering appearance when the sun is in a certain position; and the castle of Aubonne has likewise a tower of the same kind, which at certain hours makes a similar appearance to the Savoyards. The bailiwick of Aubonne contains several villages, which are mostly at the foot of the mountain Jura. In one part of this mountain there is a very deep cave, wherein those that go down find a natural and perpetual ice-house. At the bottom is heard a great noise like that of a subterraneous river, which is supposed to be that of the river Aubonne, because it first appears, with several sources, about 100 paces from the foot of that mountain.
