Ventnor is a seaside resort and civil parish established in the Victorian era on the south coast of the Isle of Wight, off the southern coast of England. It lies underneath St Boniface Down (which, at 787 feet, is the highest point on the Isle of Wight), and is built on steep slopes and cliffs leading down to the sea. The higher part is referred to as Upper Ventnor (although officially it is Lowtherville); the lower part, where most of the amenities are located, being known as Ventnor. Ventnor can sometimes include the villages of St. Lawrence and on the other side of town the village of Bonchurch. The sheltered location on the cliff of the island's south coast means the area experiences a microclimate with more sunny days than much of the British Isles, and fewer frosts. This has allowed many species of subtropical plant to be successfully planted and maintained. Ventnor Botanic Garden is particularly notable.
