Ludlow was the site of a nasty fight on April 20, 1914, between the Colorado National Guard and striking coal miners that left 21 dead (12 children, 8 adults), including 1 bystander, and 1 National Guardsman. On the site is a monument erected by the United Mine Workers in 1919.
It was built by the Jones Brothers Company of Barre, Vermont. The monument was damaged, the figures decapitated, in May 2003 by unknown vandals. The repaired monument was unveiled on June 5, 2005, with slightly altered faces on the statues. (wikipedia)
