Gather at Hoddom Castle for a led walk with the Hoddom Ranger to Repentance Tower. He will guide you through woodland and then up a short but steep climb to the Tower on the ancient beacon hill of Trailtrow. Repentance Tower was built by John Maxwell, 4th Lord Herries, as a watchtower for Hoddom Castle in the 1560s. The summit of Trailtrow provides superb views in all directions, towards the Solway the Lake District and over Annandale, and is clearly a strategic site on which to build a border tower during the uncertain times of 16C.
