Portora Castle was built in 1612 for Sir William Cole. The original castle was comprised of a three storey house with a defensive bawn and four circular towers. Whilst only the remains stand today, you can still imagine what this castle looked like in its prime.
Portora Castle was built in 1613 to guard the point where the river flows into the lough. Despite surviving sieges in the 17th century, it lies in ruins following the efforts of schoolboys playing with explosives in 1859 and later storm damage.
