Out of curiosity, I checked on Google Street View, and it appeared to be apartments. In these times, we don't always have the luxury of free-standing edifices clearly dedicated to the Faith. I would sooner assist at the Traditional Latin Mass in a simple apartment, than a dubious modern liturgy in the grandest cathedral.
Amen! If I can track it down I will. Of course any Latin mass performed in Knoxville will be in defiance of the bishops orders. I would go if it was offered.
