The unique roof of this church, St. Stephens Lutheran Church of Northglenn, CO, makes use of the mathematical shape, the hyperbolic parabaloid.

This outstanding gravity-defying structure was designed by Boulder architect Charles Haertling in 1964.

There is a webpage dedicated to Haertling’s incredible body of work.

On the Haertling site, there is a description of this church that is truly fascinating in its articulate expression of this church’s complexities.

I have previously posted photos of another Charles Haertling church, the Our Savior Parish Center.
