Under the Turks the castle appears to have long since fallen into the decay in which it now moulders. Prince Eugene seems to have found no difficulty in taking it _en passant_ during his hasty dash into Bosnia in 1697; and in 1717 it again fell for awhile into the hands of the imperialists under General Petrasch. At the present day even the Turks recognise it as a ruin, and apparently throw no obstacle in the way of those who may wish to explore it. We, at any rate, entered the old fortress unopposed, passing through a now broken archway, the former outer gate of the castle, which opens on its least precipitous side upon the neck of the hill where the present upper town of Doboj is situated. We now found ourselves in the outer yard, between the castle and the exterior walls, in a kind of covered causeway leading to the inner gateway of the castle itself. Here, groping among the rubble, we discovered an old cannon of apparently very early date, with two dolphins forming handles—an ancient trophy, we liked to think, from the Venetians; but though we looked carefully about the walls and fragments for any inscriptions or elegant details of architecture, we hit on nothing except an old square stone with an almost effaced chevron moulding round it, set in a dark and inaccessible position in the wall inside the castle-gateway, and which may have had some further device on it. Entering by this gateway, the arch of which is of ogival shape, we passed the remains of what may have been the dwelling-house of some former Turkish commandant, now in a state which makes it dangerous to the passer-by. Then clambering up among the more ancient and massive ruins, we came upon an old chamber in the wall, with a barrel-vaulting, where we discovered a quantity of rotten musket-stocks, which must have been mouldering here for centuries, and a small arsenal-full of stone cannon-balls, such as from time to time turn up on Bosworth Field. Further on we came to the tower which forms the northern corner of the castle, which is tolerably perfect inside, and in shape resembles a halved octagon. There appear to have been two other towers at the two other corners of the castle, which in shape is triangular; but I will not attempt more than a rough plan of this medley of ruins, which, half-concealed with brambles and wild vine, and tufted in every crevice with maidenhair and rue-fern, are more picturesque than intelligible.
