God's Ark of Safety is a non-denominational Christian ministry in Frostburg, Maryland, United States, led by Pastor Everett Spence. On Easter, 1976, former Pastor Richard Greene began building a replica of Noah's Ark atop a hillside along what is now Interstate 68 featuring a sign that announces to passing travelers: "Noah's Ark Being Rebuilt Here!" Ground was broken for the ark in September 1976 with over 3,000 tons of concrete. The foundation and earthwork were built to biblical proportions, around 450 by 75 by 45 feet, which is about one and a half football fields long.
