The city's particularity is that the historical centre is located on a small island which is connected to the new city by two bridges. The Old Town is a labyrinth of entangled little streets with small little squares. Following tradition, the historical centre is divided into a lower and an upper part, the separation of which dates back to the 10th century BC when the acropolis was extended towards the sea. A characteristic specific to Taranto is the geographical position of this extension: there is quite a difference in height between the two parts. Between 9m†and†12m, and sometimes even up to 20m, the height differences between Vico Cosa and Arco Cosa can be seen with the naked eye. The city's unique atmosphere is mainly influenced by its ?palace decor'. When taking a walk and looking around, you are sure to notice the monstrous shapes of the gargoyles and mascarons (Duomo and Garibaldi streets). These peculiar stone masks can be seen under the cornices and serve to drain rainwater. Finally, as you come out of the Old Town, you will come across the Victor Emmanuel II promenade. Take a moment to admire the ?palazzata', a series of grand buildings overlooking the sea.
