High and hoar on the forehead of the Jettenbühl stands the Castle of Heidelberg. Behind it rise the oak-crested hills of the Geissberg and the Kaiserstuhl; and in front, from the broad terrace of masonry, you can almost throw a stone upon the roofs of the city, so close do they lie beneath. Above this terrace rises the broad front of the chapel of Saint Udalrich. On the left, stands the slender octagon tower of the horologe, and, on the right, a huge round tower, battered and shattered by the mace of war, shores up with its broad shoulders the beautiful palace and garden-terrace of Elisabeth, wife of the Pfalzgraf Frederick. In the rear are older palaces and towers, forming a vast, irregular quadrangle;--Rodolph's ancientcastle, with its Gothic gloriette and fantastic gables; the Giant's Tower, guarding the drawbridge over the moat; the Rent Tower, with the linden-trees growing on its summit, and the magnificent Rittersaal of Otho-Henry, Count Palatine of the Rhine and grand seneschal of the Holy Roman Empire. From the gardens behind the castle, you pass under the archway of the Giant's Tower into the great court-yard. The diverse architecture of different ages strikes the eye; and curious sculptures. In niches on the wall of Saint Udalrich's chapel stand rows of knights in armour, all broken and dismembered; and on the front of Otho's Rittersaal, the heroes of Jewish history and classic fable. You enter the open and desolate chambers of the ruin; and on every side are medallions and family arms; the Globe of the Empire and the Golden Fleece, or the Eagle of the Cæsars, resting on the escutcheons of Bavaria and the Palatinate. Over the windows and door-ways and chimney-pieces, are sculptures and mouldings of exquisite workmanship; and the eyeis bewildered by the profusion of caryatides, and arabesques, and rosettes, and fan-like flutings, and garlands of fruits and flowers and acorns, and bullocks'-heads with draperies of foliage, and muzzles of lions, holding rings in their teeth. The cunning hand of Art was busy for six centuries, in raising and adorning these walls; the mailed hands of Time and War have defaced and overthrown them in less than two. Next to the Alhambra of Granada, the Castle of Heidelberg is the most magnificent ruin of the Middle Ages.
