HMP Holloway – LondonAugust 2018The recently closed HMP Holloway was an unexpectedly successful explore, with many hours wandering round the confusing and depressing corridors. Thames Valley University – SloughMarch 2018A large university tower block in the centre of Slough. Slough is normally a place best avoided, but this was a surprisingly decent explore. Flexlands School – SurreyMarch 2017An unexpected find that turned out to be a great explore. It wasn’t too long after this that the school was demolished.
