Stafford (WFVA) -- Stafford County opened up the new Stafford Civil War Park off Mount Hope Church Road over the weekend. The 41 acres is where over 130-thousand Union soldiers held winter camp before the Battles of Chancellorsville and Gettysburg. Much of the work and money to build the park was donated. 1st District Congressman Rob Wittman said the park will impact the local and state economies. "The Virginia Tourism Corporation said that at Civil War sites, visitors stay twice as long," he said. The land has remained untouched over the years. Historians say you’ll see sites you can't see today at other area battlefields. Glen Trimmer with Friends of Stafford Civil War Sites said he was told to take 30 years to research and build the park. It took just over two years. Trimmer said he wanted his grandchildren to see the park. His one year old grandson was at the ribbon cutting on Saturday.
