Is the place where the movie The Secret Garden was shot really named Misselthwaite Manor If it's not what is the name of the mansion or the whole area?

There is no stately home in the UK called Misselthwaite manner, it was a name made up for the book. The building used in the 1993 film of The Secret Garden for most of the exterior shots of Misselthwaite manner is called Allerton Castle and you can find pictures of it on the website here http://www.allertoncastle.co.uk/about_allerton.html it's located in Yorkshire and is open to the public so you can go and visit, I did a couple of years ago and they showed me the different areas where they filmed.
