The design of "vertical circulation"

Rather than writing about a specific county courthouse in Minnesota, this blog post will feature one of my favorite components of building design - the staircase. Modern courthouses, those built in the latter half of the 20th century up to the present day typically design a staircase as a functional element, or as an Instagram post I follow recently lamented, as a “means of vertical circulation.” The stairs direct people up and down between floors to the various courtrooms and administrative offices. But, let’s be honest, most visitors these days are probably taking the elevator which older buildings have added as part of upgrades that were made in the 1990s following the passage of the Americans with Disabilities Act.

In buildings from the 19th and first half of the twentieth century, the staircase was usually a grand affair. It was laid out as a stately entrance into an imposing civic structure. The steps were wide, often edged with wrought iron or carved wooden railings, sometimes leading up to a second story rotunda or a landing lit by a large arched or stained glass window. The stairs served as a gateway into the serious business of the courtrooms and county offices. Accordingly, some of my favorite interior staircases are in the older courthouses, seen more frequently outside the Twin Cities metro area. But newer courthouses, those typically from the 1930s to 1960s can have their own charm. Those designed during the Art Deco period before WWII or from the Corporate International design period after the war feature staircases of gleaming chrome, terrazzo flooring, and sleek, geometric lines.

Here are some of my favorites.

Koochiching County

Originally part of Itasca County with a county seat in Grand Rapids, International Falls, parodied as Frostbite Falls in popular culture, became the seat of the new county of Koochiching in 1904. The courthouse was finished in 1910 and features this serene staircase at its entrance.

St Louis County

Virginia became a second location for county business (the county seat being in Duluth) in 1904 when local residents advocated for somewhere closer than the distant North Shore city. The courthouse was built in 1910 and has one of the most esthetically pleasing staircases (from many angles) of all the courthouses in the state.

Rice County

The 1934 courthouse in Faribault welcomes visitors with this undulating staircase straight out of a Fred Astaire and Ginger Rogers movie.

Lake County

If you’re headed to the North Shore, make a quick detour in Two Harbors when you stop for gas. The fish scale dome of the 1905 courthouse (details coming in a future blog post) and this three-flight staircase with a stained glass window at the top landing are worth a stretch of your legs.

St Louis County

St Louis County is the biggest in the state at over 6000 square miles (twice as large as the next biggest, Koochiching). Hibbing, along with Virginia, handles the legal needs of the Iron Range while Duluth, as the county seat and largest city, handles the rest. The courthouse in Hibbing makes dramatic use of stone, chrome, and terrazzo in this floating staircase design from 1954.
