Similar to Joske Pavilion, the Koehler Pavilion is built of stone, concrete, and wood and is roofed with standing‐seam sheet metal. The overhanging roof is supported by columns that rest on stone perimeter walls. A central frame structure, covered by a hipped roof, rises in the center. The entire roofing system is supported by regularly spaced interior columns. A pavilion likely was constructed on this site shortly after Koehler Park was acquired by the city in 1915, and the perimeter wall stonework indicates that the structure dates to the period between the middle 1920s to the late 1930s. The structure was remodeled in 1982 when an adjoining concrete patio was constructed overlooking the river.
