The story of this place
The Skipsea record includes an earlier wartime observation post and an underground monitoring post opened in 1959. The underground post served as a master post for three others and reported to York’s No.20 Group headquarters.
Local visual aircraft spotting ended in 1963, while the underground post closed in 1991. The two buildings had different jobs: one needed a view of the sky, while the other provided protected space for crews using monitoring instruments.
What you can see
Historic England describes surviving fittings and damage to the older structure. These details help explain how the posts differed, but they do not provide a current assessment of their condition.
No public entrance, visitor opening or permission to enter has been confirmed. The two structures can be studied through the linked account without assuming that either is open today. We have not inspected them, and an old photograph or restoration account should not be treated as current access information.
What we still need to check
The source describes the remains at the time they were recorded. We have not checked their present condition, ownership or visitor arrangements.
