Dublin blends historic pubs, literary heritage, and youthful energy — Trinity College's Book of Kells, Guinness Storehouse, and Temple Bar define the Irish capital.
Dublin is a city of stories -- literary heritage from James Joyce to Oscar Wilde, pub culture that has defined Irish social life for centuries, and a youthful energy that comes from having one of Europe's youngest populations. Trinity College's Book of Kells in the Long Room library, the Guinness Storehouse pouring perfect pints with a 360-degree skyline view from the Gravity Bar, and Temple Bar's cobblestone streets with buskers are the highlights. The city's Georgian architecture in Merrion Square, the Grand Canal Dock tech hub called Silicon Docks, and the coastal cliff walk at Howth Head show Dublin's diverse character.

March draws crowds for St. Patrick's Day. Winter (November-February) has cheapest flights but short days with sunset around 4 PM. July and August are peak tourism season.
