Cast iron columns such as this are located throughout Building 49 and were refinished as part of the plan to preserve the character of the building, which was built in 1894. The building is receiving $5 million in renovations that are scheduled for completion later this summer. The updates will provide 32,000 square feet of office space for the 55th Mission Support Group and 55th Force Support Squadron. (U.S. Air Force photo/Delanie Stafford)
