Despite the hustle and bustle generated by Ireland's high-speed economy, Dublin remains an intimate capital that mixes elegant Georgian buildings, wrought-iron bridges, a battalion of booksellers, and more than 1,000 pubs. The heart of the city is the River Liffey, which runs east to west, splitting Dublin neatly in two. The more affluent Southside has a greater concentration of sights, and it can seem a world apart from the more working-class (though increasingly gentrified) Northside. North or south, Dublin is compact and easily navigated, making it a great walking city.
