On August 1, 1883, the eyes of the nation turned to Kentucky as thousands crowded the lanes of Louisville's Southern Extension. Tugging a silken cord, President Chester Arthur set the machinery in motion for an event that changed the town forever. Touted at home and abroad as the 100 Days that Louisville Opened Its Doors to the World, the occasion was the inauguration of the Southern Exposition, an early world's fair with a wide variety of mechanical, scientific, and cultural displays showcasing the latest advances in the cotton industry. In the first 88 days, an astounding 770,048 visitors came. As a result, tremendous growth occurred, the city's first suburb eventually sprang up, and the site became populated with a new neighborhood containing architecturally opulent residences. Known as Old Louisville today, it counts as one of the country's largest historic preservation districts, with hundreds of magnificent structures providing a glimpse into a fascinating Victorian past.
