• The lido boom and bust: how Britain built, closed and saved its open-air pools

  

  In the 1930s Britain built lidos; from the 1970s it closed them; since 2000 some have come back. I built an open register of 73 lidos: 33 of 49 dated openings came in the 1930s, and 14 closed pools have reopened.

• Britain’s last line of defence: the pillboxes and stop lines of 1940

  

  I mapped 14,690 wartime defences recorded by Defence of Britain volunteers. The planned German landing beaches had 2.3 times the average density of defence, and 71% of sites with a known condition were still standing.

• Still Standing: why do old buildings survive?

  

  I mapped all 6,837 buildings and structures in Wikidata from before AD 1100. 65% were built for worship, most still are, and the survivors are either indispensable or forgotten.
