Virginia towns list more on the Register than most of the country (a typical Virginia town has 3.6 per 10,000 residents, the U.S. 2.4), so Crimora’s 31.9 sits near the middle of its state (62% of Virginia towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.

What stands out about Crimora’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
What put Crimora on the map was the open-pit Crimora Manganese Mine that started in 1866. The mineral manganese was used in the production of steel. Mining at Crimora continued intermittently under a series of owners until March 1946. The Crimora deposit is about 500 feet wide, 200 feet deep, and half a mile long and consists of clay with scattered lumps of manganese ore. It lies under a layer of clay and quartz fragments about 15 feet thick. The Crimora deposit produced more manganese than any other single deposit in the United States and, at one time, the mining operations there were among the largest in the world.
The Crimora post office opened in 1904, the earliest record of the town by name (U.S. post office records).
