If only the ageing walls of Charleville Castle could talk! But seeing they can't, inquire if tours are available to hear a few of its tales instead.
You'll have sightseeing choices galore when spending time in Tullamore. Charleville Castle is an ideal place to start here, but there are numerous other fine attractions to explore. Charleville Forest Castle, Durrow Abbey, and Tullamore Dew Heritage Centre are close to the fortified complex and will top off your day nicely.
