Grosmont, along with its sister castles Skenfrith and White, was built to protect one of the main routes through the border region between England and South Wales. In the early twelfth century King Stephen brought all three castle together under a single Lordship that controlled the 'Three Castles' as one defensive unit.
The name "Grosmont" is derived from the French "gros mont" meaning "big hill", an apt name for the large mound on which the castle is built. By the early 15th century the castle had played its last military role and by the 16th century all three castles had been abandoned and were falling into ruin.
The castle is hidden at the back of the village houses with access to the castle easily missed, so you'll have to look out for the lane that leads to the castle. This is a fabulous castle to explore.
