Minneapolis and her Park Board, in the late 19th and early 20th centuries, had a complicated relationship with the word “pavilion.” The word means “an ornamental building, usually of light construction and designed for temporary shelter, refreshment, etc., esp. in a park […] used as a place of entertainment or recreation.”
From the earliest years of Park Board ownership of Minnehaha Falls, they worked to grow the grass. For most people, a park implies green grass lawn under mature trees. Certainly this was the accepted ideal in the infancy of landscape architecture, around the time the Minneapolis Parks system was created. Picturesque contemplation of the natural (though created) terrain was more important than playing ball, flying kites, or flower-picking.
The Park Board gained control of the Falls in 1889, the same year it created ordinances outlawing all these activities in the parks. They had a point, because back then, the falls were surrounded by barren dirt, and neither the landowners nor the businesses who rented from them cared much about growing grass.
Minnehaha had for decades been the most famous spot in Minnesota, always attracting large crowds. All those feet made growing grass unpredictably difficult for the Park Board, even with great expenses for seed and with placing “Keep Off The Grass” signs. This was a struggle every year.
