The Castle of Kenilworth is an excellent example of a midland fortress. To an ordinary observer, its site presents much of quiet sylvan beauty, but nothing of obtrusive military strength; and yet, in the hands of skilful engineers, it became, in point of size, strength, and accommodation, one of the most important military posts in England. It had walls capable of great passive resistance, a capacity for containing a numerous garrison and immense stores of provision, and a front protected by a large sheet of water, which again was covered by a formidable outwork. Moreover the midland districts were, from an early period, traversed by main and cross roads, favourable to the concentration of troops and the transfer of stores, seldom sought in vain in so fertile a country. For all these qualities, strength, capacity, a central position, and facilities for collecting and feeding a garrison, there was, in the days of its pride, no fortress in England superior, probably none equal, to Kenilworth; and now, when its grassy lawns and ivy-covered walls are redolent of peace and prosperity, and of English rural life, the thoughtful visitor cannot but feel that the place was a fitting one for the conclusion of that celebrated contest between monarchical power and civil liberty, in which, though the honour and nominal victory were with the Crown, the real and permanent gain remained with the English people. Half-way between Warwick and Coventry, where the action of water upon the soft rock of the new red sandstone has wrought the surface of the country into an immense network of low, round-topped hills and broad and gentle valleys, the Inchford brook, one of the many tributaries of the river Sow, receives, on its left or northern bank, a smaller and nameless streamlet. At the point where the waters and their respective valleys unite, a knoll, partly of rock and partly of gravel, juts out from the north-east as a sort of low headland between the two, and is somewhat farther isolated by an expansion of the valley lower down, the general effect of which is to invest the high ground with a marshy frontier upon its west, south, and south-eastern slopes, leaving it toward the north and north-east connected with larger tracts of equally raised land.
