The urban exploration phenomenon has taken the internet by storm in recent years, with adventurous amateur filmmakers from across the UK giving us a fascinating peek inside Glasgow's derelict landmarks.
While the practice is dangerous and, in many cases, against the law, urban explorers have taken us into all manner of crumbling sites, from creepy disused and abandoned asylums, hospitals, schools, police stations, factories and even zoos.
We at Glasgow Live have reported on numerous of these abandoned tours over the past few years, and we thought it might be worthwhile to pick out half a dozen of our favourites.
