Simhenge makes some nice photos and/or paintings. It's also a great place for collecting. When the player edits one of the community lots using the Edit Town option, it's description is "No one know how the ancients got these rocks to stand in this formation, but we sure are glad they did!" It is rumored that on the 13th day of play (Sims time), the player can see an alien space ship near the Simhenge in Sunset Valley.
Simhenge is a pun on Stonehenge, an odd rock formation in Southern England.
