An observant visitor to the recently updated Hotel Monaco in downtown Denver might spot a number of subtle touches in its halls and rooms meant as homages to Colorado’s rich natural resources. In the absence of such a keen eye, though, a guided tour sure helps. On a recent afternoon, the Monaco‘s general manager, Sandy Burkett, pointed out several of those touches: a color pallet and carpet and wallpaper patterns that reference the various minerals found beneath the Colorado soil and hallway lighting fixtures modeled after miners’ lamps. The details were added as part of a $6 million renovation competed at the hotel in March.
