Wales Millennium Centre, Roald Dahl Plass, Cardiff Bay, South Wales, UK - One of my favorite places to experience on our trip last year. Roald Dahl was majorly influential to my siblings and myself and we loved hearing his books read aloud in our home.
Fagans National History Museum -Since 1948 over forty original buildings from different historical periods have been re-erected in the parkland, among them houses, a farm, a school, a chapel and a splendid Workmen's Institute.
