Eastbourne is a large town, seaside resort, and borough in the non-metropolitan county of East Sussex on the south coast of England, east of Brighton. Eastbourne is immediately to the east of Beachy Head, the highest chalk sea cliff in Great Britain. With a seafront consisting largely of Victorian hotels, a pier, and a Napoleonic era fort and military museum, Eastbourne was developed by the Duke of Devonshire from 1859 from four separate hamlets. It has a growing population, a broad economic base, and is home to companies in a wide range of industries.
