Missouri S&T Stonehenge is a partial reconstruction of the original Stonehenge monument located on Salisbury Plain, in southern England. Missouri S&T's version of the ancient structure is located on the northwest corner of campus, and was dedicated on June 20, 1984, during the summer solstice. It features a 50-foot (15 m) diameter ring of 30 stones around a horseshoe of five trilithons through which various sightings of sunrise and sunset can be made.
