Restoration workshop
From BTMM_Wiki
The Museum's Restoration Workshop is not a public-access area.
The Restoration Workshop (at the back of Arch One) is stocked with tools and chemicals that make it unsuitable for members of the public. It also typically contains pieces undergoing delicate and exacting restoration work that often requires a dust-free environment. The Museum recognises that the public finds the restoration process interesting, but it regrets that, as an active workspace, the workshop has to be strictly out of bounds to anyone but authorised users.
