On this day in 1893, The World's Columbian Exposition (also known as the Chicago's World Fair) opened its doors to the public. The fair lasted from May 1st, 1893 until October 30th, 1893 and was visited by a total of 716,881 people. Although the fair was meant to be temporary, several of the fair's structures still exist including one right here in Milwaukee. The Pabst Trade Pavilion, which was designed by Otto Strack, was located inside the fair's Agricultural building. After the fair, Captain Frederick Pabst had the structure dismanteled and shipped to Milwaukee where it was attached to his Wisconisn Avenue mansion. You can learn more about the Chicago World's Fair and the Pabst mansion at your Milwaukee Public Library.
