If my memory serves me right, the stained glass behind the baptismal pool depict a paradise scene similar to those seen in the WT books. There are other murals in the atrium between each door leading in the auditorium but I can't remember what they depict. I have not been in that building for 16 years...but I was involved in its construction and attended the 2 day dedication program.
The picture on the preceeding post is one of the 18 feet tall murals in the glass atrium...the floor is black marble imported from Italy.
