Lacy's Caves are a series of five chambers in the red sandstone cliff of the River Eden, just north of Little Salkeld, Cumbria, England, near Nunnery, Cumbria, at grid reference NY564383. They are named after Lieutenant-Colonel Samuel Lacy of nearby Salkeld Hall, who commissioned their carving in the 18th century. The reason for their creation is unknown; however, they were used by Lacy for entertaining guests, and the area was originally planted with ornamental gardens.
