Opposite Christ Church Cathedral is Dublinia, a museum with displays on Medieval Dublin and the city's Viking past. It's the perfect place for a family outing as the museum is interactive, allowing you to see, touch and even smell old Dublin. Take the opportunity to climb up St. Michael's Tower (dating from the 17th century), which affords incredible views over the city.
