Designed by John D. Atchison, that structure followed the early prairie style of architect Frank Lloyd Wright.

This original Pavilion building, having suffered from previous structural issues as well, was ultimately destroyed by a fire in May 1929.

[4][3] The current, larger pavilion, designed by architectural firm Northwood & Chivers, was opened on 24 May 1930.

In 1969, the refreshment facilities on the main floor were renovated, with space added to house a souvenir shop and a park museum.

[4][5] After a large-scale renovation in 1998, the Pavilion Gallery Museum was opened in the building alongside a restaurant called Tavern in the Park.
