It was also used for church and town meetings until 1894 when the Old Stone Church was built. In 1979, it was saved from demolition and converted into the town's history museum by the Lyons Historical Society.

The town has large red sandstone mountains on three sides. Its rock, from the Permian period, about 260 million years ago, is considered the hardest sandstone in the world, and has a unique red or salmon color. While E. S. Lyon established the quarrying business in the town, his business was not a big success, and he left for California. Numerous owners succeeded him and developed various successful quarries over time. Murphy, Brodie, Ohline, Loukonen and Vasquez are among the most noteworthy owners. A railroad built to the town in the late 19th century gave the quarries a significant boost.
