Hi guys!
Firstly, the web-site is fantastic and I wish you every success with it.
I wondered if you had come across any info relating to the building which sits at the corner of North Hanover street and Cathedral street (now part of the Buchanan Street complex car park).
My wife works at Strathclyde University and has heard from various people that it is a lift/ventilation shaft associated with a deep-level tunnel which runs under that part of the city. I could be getting my stories mixed-up but the tunnel may be related to a complex beneath the Royal Infirmary. The Royal Infirmary part of the story came from someone my wife knows who worked there and often had to visit the hospital mortuary. She says that the mortuary occupied a very small part of a considerable network of tunnels, one of which runs South under the city, possibly via the shaft at North Hanover Street/Cathedral Street.
I find this story very interesting and I hope it is of some interest to yourselves. Any light you could shed on it would be much appreciated. In the meantime, I'll keep asking around for more evidence and would be delighted to contribute to a possible project for your site if I can gather enough info.
Regards,
Dave.
