No sign. No markings. After all the management doesn't have to care, as they are paid the same if there is a million visitors, or only the artist and the artist's family. Actually, many visitors would be too much trouble, so why bother? Closed for weeks, sparsely located art, the space is simply too large for what they usually exhibit here.
Also, there is are only a few parking spaces, and those are taken by the employees, or the locals living in the buildings near the hall.
