EAST YORKSHIRE, ENGLAND—BBC News reports that three archaeological sites were discovered by researchers associated with Yorkshire Water during a sewer construction project in northern England. The first is a well-preserved circular monument containing human remains thought to be about 4,500 years old. The remains were buried in a crouched position and then were likely covered with burned stone and charcoal to form a dome-shaped mound. The second site features parts of a Roman road flanked by drainage ditches. This road likely traveled to the nearby Roman town of Derventio. The third site features a burnt mound, including a small oven and a deep pit thought to have been used as a wood-lined well.
