Sunken Garden in Lincoln, Nebraska
Built in 1930, the Sunken Gardens was a Depression-era project, built on a former abandoned neighborhood dumpsite. As a part of a city program helping unemployed men to earn money, the "Rock Garden," as it was originally called, reflected the popular 1930s trend for rock gardens in progressive communities. Rocks were used for the garden's skeleton and for structures like water fountains and retaining walls at different heights to create terraced levels. Today, Lincoln’s Sunken Gardens is one of the "300 Best Gardens to Visit in the U.S. and Canada" in the National Geographic Guide to America's Public Gardens.
