The earliest known photographs showing the southeast side of the courthouse square in Glen Rose include the modest I.V. Willingham Store. Oral traditions state that it was built during the 1880s, and it clearly is one of the oldest surviving buildings in the downtown district. As can be seen from its two ends, the structure began with a gable roof that ran its whole length. This arrangement was changed to the current angled roof after construction of the adjacent building created drainage problems. The Willingham Building, long used for commercial sales, has housed a remarkable variety of enterprises. Over the years sellers of dry goods, general merchandise, ladies fashions, and livestock feed have operated within its walls, as well as several restaurants. The variations and visible changes in the stonework comprising the long, exposed wall facing East Walnut Street show evidence of the multiple uses that this adaptable building has served over the last 125 plus years.
