Belsay Hall Castle: This is a 14th century medieval castle. The main structure, a three storey rectangular pele tower with rounded turrets and battlements, was constructed about 1370. In the 30 acres of stunning Grade I gardens, unaltered for 200 years, you'll discover thousands of exotic species, famous rhododendrons and the magical Quarry Garden, with ravines, pinnacles and sheer rock faces inspired by the quarries of Sicily.
