At first we thought it was mirage, which had hitherto often deceived us by its distortion of forms and exaggeration of heights, but as we paddled on against the wind we soon saw it was a collection of solid architectural forms. It was, however, only when we were within a mile or so of the town that we recognized in what we had taken to be a modern landmark the huge towers and walls of the great mediæval citadel of Semendria (Smédérévo, in Servian), rising in all their ancient dignity from the very waters of the Danube, and overtopping with their masses of solid masonry the little town modestly nestling in the shadow of the great fortress. Of recent years Semendria has become of commercial importance as a shipping port for grain, and when we entered the town its narrow streets were blocked by hundreds of laden ox-carts, all patiently waiting their turn at the public scales, where the weight of the grain is guaranteed by the town officers before it is delivered to the lighters. Through a motley crowd of Servians in barbaric fur caps, red sashes, rawhide sandals, and the coarsest of homespun garments, we made our way to the fortress. The great walls enclose a triangular space of ten or twelve acres, occupying the whole of a low point between the River Jessava and the Danube. The apex of the triangle at the junction of the rivers is a citadel of great strength, built in 1432 by the despot George Brankovitch. It is still in wonderful preservation. Indeed, the walls of the whole enclosure and the twenty-three great square towers show remarkably few signs of decay, and, with the exception of the destruction of the wooden platforms, are almost as sound as the day they were built. Here and there an inscription, or a fragment of a statue built into the walls, proves that the importance of the town dates as far back as the Roman occupation, when this was undoubtedly one of a series of strongholds along the river. The barracks of the Servian garrison which stand in the great enclosure appear like huts in comparison with the immense towers and high walls of the mediæval structure, and a regiment of infantry may be quite lost sight of among the tangled bushes and the thick foliage of the trees which cover a large part of the ground. From the top of one of the great towers we saw below and before us a panorama of varied beauty, extending from the heights of Belgrade to the Carpathian range, faintly shadowed in the distance beyond the glittering expanse of the Danube, which spreads out into great broad reaches, with numerous islands, and, like its smaller self among the mountains of Baden, pauses and gathers volume and strength for the dash into the great gorge that cleaves the jagged mass of mountains for fifty miles or more before again resuming its quiet flow.
