The American Civil War Museum on Monday unveiled preliminary designs for its new museum building in Richmond.

The new building, a joint enterprise of the Museum of the Confederacy and the American Civil War Center at Historic Tredegar, is to be built at the site of the Tredegar Iron Works on the James River.

Groundbreaking is tentatively set for early next year, and the new museum could be open by July 2016, according to a museum announcement.

As a result, Historic Tredegar’s “In the Cause of Liberty” exhibit, located in Tredegar’s foundry building, may close as early as Thanksgiving to make way for construction, the announcement said.
