In 1989, Kerr County native Doug Hill finished work on the back patio on his Hunt, Texas, property and had one extra limestone slab, which he jokingly offered to his friend and neighbor Al Sheppard, who accepted it and stood it upright in the middle of his pasture. Hill and Sheppard liked the look of the monolith and built an arch around it, and the 13-foot arch reminded them of Stonehenge in England. Sheppard then formed a vision for their own Stonehenge II and contracted Hill to build it. The original Stonehenge in Wiltshire, England, was erected around 2500 B.C. and is believed to have functioned as an important site for religious or astrological ceremonies. Hill and Sheppard's project took about 9 months to complete, with Hill fabricating the stones from steel, metal lathe, and plaster and anchoring each with cement. Stonehenge II is 90% as wide and 60% as tall as the original. Later, after visiting Easter Island off the coast of Chile, Sheppard was inspired to add two 13-foot-tall Moai head statues. Sheppard died in 1994, and his property remained in the family. In 2010, the Sheppard family donated Stonehenge II and the Moai to the HCAF in memory of Al, a longtime supporter of the organization, and after funds were raised, the structures were moved to their current home on this campus in 2012.
