Next to the cathedral and sharing an extensive 18th-century jail complex, the St. Patrick Centre and the County Museum provide some intriguing glimpses into the rich history of this area. The surprisingly high-tech exhibits put everything into context. There's a 180-degree film (which, according to the center, can give some people motion sickness). You'll also be introduced to some of the county's more notable figures, from St. Patrick to a handful of prisoners sent off to Australia in the 19th century.
