image creditHartman's Historical Rock Garden in Springfield, Ohio, USA, is an art project that dates from 1932, when Harry George Hartman lost his job during the Great Depression. The molder occupied his time with creating rock sculptures in his back yard, spanning all sorts of themes. Religion, historic buildings, recreations of famous battles and hundreds of thousands of stones.
Mr. Hartman died in 1944, but his wife Mary took over custodianship of the Rock Garden, welcoming visitors from around the world. When she died in 1997, the garden fell into decline, but was rescued and re-opened in 2010.
