NACOGDOCHES, Texas – Stephen F. Austin State University is doing some needed maintenance to its downtown art gallery, The Cole Art Center @ The Old Opera House. SFA workers will clean the outside brick and remove deteriorating grout to apply new material and sealant to prevent seepage that has caused some damage to interior upstairs offices. The overhead entry awning will also be repaired and restored to prevent leakage. As a result of the work, Cole Art Center will be temporarily closed for about two weeks. When work is completed, patrons will still have opportunity to view the Texas National exhibition through June 30.
