Waterford is the oldest town in Ireland and stands on a triangle of land bounded by two rivers. It was the perfect location for a Viking settlement interested in trade. Ragnarl’s (Reginald’s) Tower is the most prominent remnant of this once thriving city. Over the course of its history it has also been used as a mint and a prison. High on the exterior wall of the tower, a cannonball remains embedded in the wall, a souvenir of one of the numerous attacks the city sustained.
Onward to Trim Castle, a large Anglo-Norman castle complex with a massive keep of 4 floors, situated in the centre of the space and has the only remaining barbican entrance in Ireland. The moat still surrounds the castle, while a unique entrance through the wall exists on the river where goods were delivered to the kitchens and store rooms via barges.
