"The city in its setting and entire surroundings may be said to have something ideal." (Johann Wolfgang von Goethe, 1797). Scarcely any other European city has had its praises so often sung as Heidelberg. The mysterious Heidelberg Castle, the picturesque Old Town, and as Goethe himself stated, the perfection of its setting – in the nineteenth century, all of this attracted the German romanticists, who immortalized Heidelberg in poetry, music, and art. Today the charm of Old Heidelberg is combined with a future-oriented and international focus.

The narrow and often steep granite-paved streets of Cagliari’s Castello District are a reminder of a bygone age when the town was dominated at first by Pisans, and later by the Aragonese. Built from white limestone, the walls and towers of the Old Town shimmer in the sun and are a magnificent sight, especially if you are lucky and approach the city from the sea, as the English novelist D.H. Lawrence did in 1921 when he described the Old Town as looking like a "Jerusalem without trees".
