The first oddity discovered was this impressive pillbox, the original blast walls demolished allowing direct
access to the main shelter. Inside the enormous embrasure at the front pointed directly to the junction of the
Shelford Road with the Cambridge main road.
The embrasure had since been bricked up, but this Type 28 pillbox would've held a massive anti-tank gun. This
fitted with Major Tom mentioning that an anti-tank trap was located elsewhere on the site.
The pillbox had been converted to a substation of sorts in later years, with 415V distribution, pumps
and pipework gently rusting away.
