Hastings
Hastings is a town and Borough on the coast of East Sussex in England. It includes originally separate settlements, as well as the inevitable growth of the town through the building of new estates.
St Leonards-on-Sea
St Leonards-on-Sea (or for short, St Leonards) is part of Hastings, East Sussex, England, lying immediately to the west of the centre. The original part of the settlement was laid out in the early 19th century as a new town: a place of elegant houses designed for the well-off; it also included a central public garden, a hotel, an archery, assembly rooms and a church. Today's St Leonards has extended well beyond that original design, although the original town still exists within it.
