The four-acre site in the Yorkshire Dales has been transformed into a labyrinth of tunnels, chambers, follies and surprises.
What is the Forbidden Corner?
Originally laid out as a private folly, the Forbidden Corner's quirky features led to demand for it to be opened to the public. It's got a huge pyramid made from translucent glass, paths and passages that lead nowhere, bizarre statues, and tricks at every turn.
It began as a small wood of fir trees planted to act as a windbreak for the stables at the Tupgill Park estate in 1979. In 1989, owner Colin Armstrong decided to create a walled garden to provide views of the Coverdale valley. A grotto was built, incorporating ideas from all over the world, and by 1991 the boulder canyon was added. The first visitors to the then-unfinished grotto were a group of students from the University of Hull in 1993.
Hedging for the maze was then planted and the Face Tower, which welcomes guests, was built. In 1994 the attraction officially opened to the public, and a gift shop and cafe were later added.
