Yes, this is not an April Fools Joke. This Mushroom-looking House at the Winterthur Country Estate and Museum in Montchanin is actually called the Tulip Tree House, and it is located in the Enchanted Woods portion of the estate’s gardens. The Enchanted Woods and Tree House were built in 2000 and 2001 as a family-friendly, fairytale addition to the gardens. The tree house was modeled after an 18th century illustration of a hollow-tree tea house. Photo by xzmattzx.
