Concrete City was built as employee housing in 1911 and abandoned just 13 years later in 1924. The 20 duplexes were made entirely of concrete and hence incredibly durable. Unfortunately they were also very drafty, cold, and held too much moisture be be long term dwellings.
In the decades that followed nearby fire and police departments have used the site for training. Graffiti writers and artists have left their mark all over, and more recently paintball and airsoft tournaments have been held here.
