The town of Corfu stands on the broad part of a peninsula, whose termination in the Venetian citadel is cut off from it by an artificial fosse formed in a natural gully, with a salt-water ditch at the bottom, that serves also as a kind of marina known as Contra-Fossa. The old city having grown up within fortifications, where every metre of ground was precious, is a labyrinth of narrow streets paved with cobblestones, sometimes tortuous but mostly pleasant, colourful and sparkling clean. These streets are called "kantounia" and the older ones sometimes follow the gentle irregularities of the ground while many of them are too narrow for vehicular traffic. There is promenade by the seashore towards the bay of Garitsa, and also a handsome esplanade between the town and the citadel called Liston where upscale restaurants and European style bistros abound. The origin of the name Liston has several explanations: many former Venetian cities have a square of that name, coming from a Venetian word meaning evening promenade, but it can also refer to the closed-list aspect of an up-scale area reserved to the nobility registered in the Libro d'Oro.

The citadel was depicted on the reverse of the Greek 500 drachmas banknote of 1983-2001.
