Ulrome Seaside caravan park pillbox: 4th December 2013 [TA 17394 57505].
Concrete base north of Atwick, measured at 2.44 metres from the cliff base on 26 May 2013 [TA 19286 51981]. This is not a wartime remnant but was once part of a North Sea gas facility constructed in 1973–5 and extended in 1983.

The most vulnerable part of a pillbox of the ‘lozenge’ type is the L-shaped (anti-)blast wall designed to protect the entrance during enemy attack. If the wall is not broken off during descent of the cliff then it is unlikely to remain attached for long under pounding by the waves. East Newton: 16th February 2014.
Every pillbox picture gallery begs an interior shot. The central wall of the unit not only supports the roof but helps protect occupants from ricochet in the event of attack. Here, sediment fills the inside almost to the embrasures (openings from which to fire a weapon). East Newton: 16th April 2014.
East Newton’s larger unit (not strictly a pillbox – it served as a generator room for the chain home low radar network) on its descent to the beach: 16th February 2014. Before the cliff line receded, the structure was used as an animal shelter.
Slide path of above: 16th February 2014. Vertical displacement is actually greater than the picture may suggest because the section of cliff itself is slipping.

Hilston: 28th September 2013.
Tunstall: 24th September 2011 [TA 31192 31960]. On top of a (locally) standard lozenge pillbox sits an additional structure dating from the Cold War. This is an Orlit post, named after the manufacturer and erected by the Royal Observer Corps. The seaward side is shown, distanced 39.7 metres from the cliff edge in Google Earth imagery for 2003, and 25.8 metres at the date here. One to watch.
Part of the top structure has collapsed since the picture was taken. The cliff edge was measurement as being 19.7 metres away on 13th May 2015, after a recent loss through a single failure of 2.7 metres.
