Mile Hi Church Sanctuary
The Mile Hi Church Sanctuary is a 233-foot (71 m) diameter by 63-foot (19.2 m) tall Monolithic Dome. It is the third, and largest structure on the Mile Hi Church campus in Lakewood, Colorado. The huge dome required a 55,000 square foot (5100 m²) inflatable Airform membrane. The sanctuary seats 1,500 with plans to add a 600 seat balcony. The wooden stage features movable towers and platforms and can accommodate a 140-member choir.

The first church sanctuary was an earth-bermed concrete thin-shell structure constructed in 1973. The new Monolithic Dome sanctuary opened in April 2008.
