The road from Mellifont Abbey to Ardee passes through Monasterboice, home to some of Ireland's finest medieval High Crosses. Near the village's Round Tower, you'll find the famed Muireadach Cross and, nearby, the West Cross, the tallest in all the country. Once you take in these noted medieval sculptures, continue on to the market town of Ardee, found at the northern edge of the Pale. Here stand two 13th-century castles:
Ardee Castle and Hatch's Castle. The town of Ardee (Baile Átha Fhirdia or Ferdia's Ford), interestingly, was named after the ford where the mythical folk hero Cuchulainn fought his foster brother Ferdia. There's a statue depicting this battle at the start of the riverside walk.
