The Simhenge (also known as Stonehenge) is a place hidden in the maps of Riverview and Sunset Valley. 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!" Simhenge is a pun on Stonehenge, an odd rock formation in Southern England.
