LOUISVILLE, Ky. (WDRB) -- A big downtown office building is up for auction.

The old Bank of Louisville building at the corner of 5th Street and Broadway is almost completely empty. 

The 11-story building dates to the 1960s. It was sold in foreclosure three years ago for $1.5 million. Now the investors want to sell it -- and they've set no minimum price.

The auction is in late September.
