This cache is NOT at the posted co-ordinates. It is a bonus to the Glasgow's Merchant City Lab Cache.
This cache is hidden at another historical Merchant City building, which we were unable to include in the Lab Cache. Its history and uses over the years can be found easily on-line.
Once you complete the Lab Cache on the separate "Adventure Labs" app, you will be given the final co-ordinates for this cache.
Good Luck!
