In the Salt Lake Temple , the walls in the various rooms are covered with beautiful
murals. While the temple is not open to the public (only church members in good
standing may enter), many smaller renditions of the murals can be seen in the
work of the 5 art missionaries sent to Paris to prepare by studying with the masters of the Paris art scene. They were to return and paint appropriate murals on the walls.
The most prominent among them was a Swiss-born artist, John C. Hafen. You can
find out much more about him by Googling John C. Hafen, or Utah impressionism.
