Other features on the capitol grounds include Sprague Fountain and the Wall of Water. The Wall of Water is located across Court Street from the main entrance. It was added in 1990 and has 22 nozzles shooting water into the air in a plaza that also has slabs of stone with information about Oregon's history. Added in 1985, the "Capitol Beaver Family" sculpture represents the state animal. Additional features of the grounds include a peace pole donated by the Society of Prayer for World Peace, a large boulder that once lay along the Oregon Trail, a planter that spells out "Oregon" using shrubs, and a rose garden maintained by the Salem Rose Society.
