The Mile High Tower, the last remainder of world renowned master
architect I.M. Pei’s 1956 creation, the Mile High Center. The glass
and metal design is in a style referred to as Miesian, from the name of
architect Ludwig Mies van der Rohe.

Mile High Tower formerly opened to a plaza on the east side, which
included a pool covered with a hyperbolic arch. The plaza is gone
and now the building seems lost as part of the Norwest Plaza.

Another famous Colorado loss of I.M. Pei design was the hyperbolic paraboloid roof of the pavilion at Zeckendorf Plaza (now Adam’s Mark Hotel).

Some of I.M. Pei’s work in Colorado survives, such as the 16th Street Mall in Denver and the outstanding N.C.A.R. building in Boulder.

The photo above shows the Amoco Tower reflected in the glass.

The black and white aluminum panels interweave to form a unique
pattern. Lights pointing upward highlight the verticals.
