This site, on a low sandy cliff known as The Horn, had once had a Martello Tower on it. The Towers which were built from 1804 onwards were designed to stop a French invasion but were also used by the Coastal Blockade to prevent smuggling. The Coastguard replaced the Coastal Blockade but continued to use this site.
The Colonnade was built here in 1911 and the Coastguard Cottages were demolished in 1934 to make way for the De La Warr Pavilion
