Ground has been broken for a $16 million arts center in Abingdon showcasing southwest Virginia’s cultural, musical and artisan heritage. Gov. Timothy M. Kaine says center, called Heartwood, will be a portal to the region’s cultural and heritage attractions, including the Crooked Road and the Artisans Trail of Southwest Virginia. The 28,000-square-foot facility will include artisan galleries, food court and an area for musical performances. It’s expected to draw 270,000 visitors annually.
