I'm told by fellow urban explorer Josh that Three Sisters used to be a ladies' department store. I was intrigued, but when I looked up the phrases "Three Sisters," "department store," and "Baton Rouge," on Google, all that came up was obituaries. Apparently a popular job for Southern ladies who died recently was working in department stores. Also, a lot of them had three sisters.
The HQ for Jimmy Swaggart Ministries is in Baton Rouge.
It is still occupado. However, not all the buildings on its campus are. This never-completed dorm for the Jimmy Swaggart Bible College has a fence around it, so because I am a law-abiding citizen, these like, other guys named Cosh and Jo supplied me with photos.
