It has already been said that this ancient and historical building stood against the bosom of the mountains, at the distance of a short league behind the town of Vevey. All the elevations of this region are so many spurs of the same vast pile, and that on which Blonay has now been seated from the earliest period of the middle ages belongs to that particular line of rocky ramparts, which separates the Valais from the centre cantons of the confederation of Switzerland, and which is commonly known as the range of the Oberland Alps. This line of snow-crowned rocks terminates in perpendicular precipices on the very margin of the Leman, and forms, on the side of the lake, a part of that magnificent setting which renders the south-eastern horn of its crescent so wonderfully beautiful. The upright natural wall that overhangs Villeneuve and Chillon stretches along the verge of the water, barely leaving room for a carriage-road, with here and there a cottage at its base, for the distance of two leagues, when it diverges from the course of the lake, and, withdrawing inland, it is finally lost among the minor eminences of Fribourg. Every one has observed those sloping declivities, composed of the washings of torrents, the debris of precipices, and what may be termed the constant drippings of perpendicular eminencies and which lie like broad buttresses at their feet, forming a sort of foundation or basement for the superincumbent mass. Among the Alps, where nature has acted on so sublime a scale, and where all the proportions are duly observed, these debris of the high mountains frequently contain villages and towns, or form vast fields, vineyards, and pasturages, according to their elevation or their exposure towards the sun. It may be questioned, in strict geology, whether the variegated acclivity that surrounds Vevey, rich in villages and vines, hamlets and castles, has been thus formed, or whether the natural convulsions which expelled the upper rocks from the crust of the earth left their bases in the present broken and beautiful forms; but the fact is not important to the effect, which is that just named, and which gives to these vast ranges of rock secondary and fertile bases, that, in other regions, would be termed mountains of themselves.
The castle and family of Blonay, for both still exist, are among the oldest of Vaud. A square, rude tower, based upon a foundation of rock, one of those ragged masses that thrust their naked heads occasionally through the soil of the declivity, was the commencement of the hold. Other edifices have been reared around this nucleus in different ages, until the whole presents one of those peculiar and picturesque piles, that ornament so many both of the savage and of the softer sites of Switzerland.
