The National Museum of Ireland is a great place to spend a rainy afternoon in Dublin. The museum has several locations throughout the city, each with its own focus. The Archaeology Museum, for example, has exhibits on ancient Ireland, including the Vikings and the Celts. The Natural History Museum has exhibits on Irish flora and fauna, including a giant deer skeleton. And the Decorative Arts and History Museum has exhibits on Irish history and culture, including the Easter Rising of 1916.
