Dublinía is an interactive exhibition exploring Dublin's Viking and medieval history, housed in the Synod Hall, a Gothic Revival building from 1875. The museum recreates period atmospheres with full-scale reproductions of historical Dublin, complete with authentic sounds and smells. A covered bridge connects it directly to Christ Church Cathedral, making it straightforward to visit both attractions in one outing. What to see includes authentic reconstructions that bring the city's early centuries to life.
