How would you like to visit a garden where every plant can potentially kill you? The gardens at Alnwick Castle in England have such a thing and you can actually go on a tour through this morbid attraction for only 16£!

The garden was apparently created back in 1750 by the 1st Duke of Northumberland and flourished until it was closed in 1950 after being used to provide provisions for people during the second world war.

The garden was revived back in 1997 by Jane Percy, Duchess of Northumberlan and opened to the public in 2001. The Poison Garden was added in 2004. The gardens get roughly 800,000 visitors per year.

Visitors can go on a small guided tour of the Poison Garden of 20 people or less. Picture: Margaret Whittaker, Alnwick Castle.

As you can see from the photo, some of the plants are in the open and some are in cages for protection.

Make sure you don’t try to visit in the winter time as Alnwick Castle is only open daily between 29th March and 28th October 2018.
