The Ol' Barn is a members-only land den that was first released in the Den Shop on January 19, 2012. It went on clearance during July 2016, but it returned to stores on April 27, 2017.
This den is a red barn that has a typical farm theme with hay bales and a wheel barrow. There is a main dirt floor and an upper wooden floor that can be accessed from a ladder on the left. A large grassy area fills the right side of the den and is bordered by a wooden fence and piles of hay in the background. The wallpapers and floor tiles for this den are all either horse or desert themed.
- It went on clearance during October 2012 and returned for a second release in March 2013.
- This den was introduced following the release of the Horse animal.
- The Horses Only Party uses a background similar to this den, but the party has a horizontally-flipped layout and includes a side entrance with a mud pool that is not found in the den.
- Ol' Barns are the second dens to be based on an animal. The first was the Volcano Den, which was based on the Wolf.
- When Ol' Barns were first removed, they were replaced by the Snow Fort.
- Many of the wallpaper and flooring patterns have a unique American-frontier/Old-West theme, for example: the Rainbow Pink walls that include horseshoes; the Lava Floor that includes cowboy boots, cowboy hats, sheriff badges, and horseshoes; the Dust Striped Walls includes wanted posters of the Bunny, Tiger, Rhinoceros, Elephant, Koala, and Horse.
- As with most dens, there is no unique pattern for the Starry Walls or the Coral Canyons Floor when used in this den.
- The den is used for one of the Jammer Parties.
