Mormon Temple Christmas Lights

When we drive around the beltway (DC's version of the M25) we always know we're nearly home when we see the Mormon temple appear through the trees.  We've been meaning to go to have a look at it for ages because it's a really unusual looking building.  At Christmas they light the whole area up with lights so this evening we went to have a look.  We didn't actually go in the temple, we'll go back in the daytime at some point to do that but we wondered around the grounds looking at the lights.
