At some time Column 258 (arrowed) vanished. See the hole in the nearby raker column caused by abrasion of the sand and shingle in the 2006 photo. When a column wears through it collapses. David Spooner (The Project Manager) and Roy Beeley are digging for Column 258 and looking for evidence of the pile top so a replacement column could be installed there. This was the start of the repairs to Hastings Pier in August 2013.
