Gov. Robert Ehrlich presented more than 50 Maryland organizations with $20 million in grants on Wednesday in order to preserve state history.

“We love to talk about our U.S. history,” Ehrlich said. “You cannot talk about history without Baltimore.” Through the Heritage Preservation Tax Credit Program, sponsored by Maryland Historical Trust, “certified heritage structures” ? those deemed worthy for the National Register of Historic Places ? will receive state income tax credits equal to 20 percent of authorized rehabilitation costs.
