which rise softly just to the south. From the glass-wall top of the Guinness Storehouse in the heart of town, the sight of the city, the bay, and the mountains will take your breath away. From the city's noted vantage points, such as the South Wall, which stretches far out into Dublin Bay, you can nearly get a full measure of the city. From north to south, Dublin stretches 16 km (10 miles); in total, it covers 28,000 acres—but Dublin's heart is far more compact than these numbers indicate. Like Paris, London, and Florence, a river runs right through it. The River Liffey divides the capital into the Northside and the Southside, as everyone calls the two principal center-city areas, and virtually all the major sights are well within less than an hour's walk of one another.
