Went to Hartwood hospital last friday. Near Shotts, east of a village called Bonkle. Like so many other old mental institutions, this ones quite cool. Built in 1890 it's in very good nick (many surrounding buildings demolished though and entirely gone.). Area still in use for laundry purposes (!) but the boarding is new and seems to be a continual attempt at keeping it clean. There's also a small bowling green- i kid you not.
Better than the hospital is the nurses quarters, three/four storey C block down from the actual hospital- again in good nick. It's a dead cert it's being kept for development (can anybody say 'luxury flats'!)
On the practical side, i think its alarmed and the drainpipes are greased.
On the worth a peek side- it's >100 years old, the roofs intact and its out the way.... and it's currently vacant.
Go forth people, and conquer.
