Medieval castles and cathedrals, traditional pubs and parks – Dublin has the lot. Ireland's capital packs in art, culture and plenty of character, always leaving you wanting more. Architectural splendours on display include Dublin Castle, built in the 13th century, and St. Patrick's Cathedral. Take a picnic to the landscaped St Stephen's Green and huge Phoenix Park, spend your afternoon spotting animals in Dublin Zoo or get clued up on Irish heritage and culture in the National Museum of Ireland. The best part? The city's almost entirely walkable – nothing's more than a 30-minute stroll away – so despite its wealth and diversity, it retains a charming and traditional small-town feel. Dinky cafes and quirky shops? Yes, it's got those, too.
