The “Celtic Tiger” is roaring here in the capital of the Republic of Ireland. The literature, music and dance of the Emerald Isle have caught on worldwide with the same vigor as her booming economy, making this elegant old town a hot “new” destination. Admire the stately 1700s Georgian architecture of places like Trinity College, home of the ninth century Book of Kells, or take in the numerous hip pubs, stores, cafes and museums brimming with vibrant young people. Dublin is easily strolled and endlessly entertaining, a city for the ages, both ancient and new.
