Wichita Falls heroes take the Recognition Roadtrip Bottle to see the World’s Smallest Skyscraper located in downtown Wichita Falls. The building, completed in 1919, is forty feet high, ten feet wide and sixteen feet tall – but why so small? As the story goes, the man who built the little skyscraper, JD McMahon, originally promised a unique skyscraper that would be the jewel of Wichita Falls – 40 stories tall, 100 feet long and 160 feet wide. But instead of being built to the square foot…the skyscraper was built to the square inch.
