The fortifications extend upwards on a rock from the Danube in the form of steps.

The city itself, with its graceful minarets, lies half a mile farther inland.

Here I saw the first mosques and minarets.

The mosques, as far as I could observe from the steamer, are built in a circular form, not very high, and surmounted by a cupola flanked by one or two minarets, a kind of high round pillar.

The loftiest among these buildings is the palace of Prince Milosch.
