The Ballykeel Dolmen, also known as the "Witch's Chair", stands alone on the edge of a green river terrace and invites you to take a look back into the past. With its three supporting stones and the imposing capstone, over three metres long, the dolmen looks like a stone sculpture left behind by a long-forgotten culture. The simple but distinctive tripod shape is a testament to the archaic construction that attracted people to this place over 4000 years ago. Excavations around the dolmen have uncovered the remains of a stone mound and Neolithic pottery that tell of the rites and customs of this early community. When you stand among the stones, you feel the mystique of the place - a place that inspires the imagination then and now. Nearby you will find other megalithic structures such as the Portal Tomb of Aughadanove, which together reflect the rich archaeological heritage of the region.

As soon as you cross the gentle ridge of Slieve Gullion, the North Cairn stretches out before you - a slightly smaller hill than its southern neighbour, but no less impressive. The stones that gather here seem like silent sentinels, witnesses of the distant Bronze Age. Two ancient stone boxes were once found here during excavations, which lay hidden in the depths of history. The North Cairn, with its diameter of around 18 metres, invites you to pause for a moment and enjoy the peace. But it is not just the Cairn that is fascinating. Right next to it lies "Calliagh Beara's Lough", a quiet mountain lake that, according to legend, is the home of the witch Beara. On a clear day, the sky is reflected in the calm waters and you can almost feel the ancient magic of this place coming to life. The road here may be rocky, but the landscape rewards with sweeping views and a touch of mysticism that makes Slieve Gullion something special.

Due to its privileged location, this incredible Anglo-Norman castle can be seen from miles around. It is believed to have been built in the first half of the 13th century by Lady Rohesia de Verdun after her husband's death. According to legend, she promised to marry the architect who built her a castle in Roche. When this happened and the architect claimed her hand, she threw him from one of the windows, which is known as the 'murder window.'
