North & South Location in honour of Elizabeth Gaskell's 200th Birthday!

If there are any fans of the 2005 BBC adaptation of North and South, and I know you are out there, you will recognize this location as the park where Margaret meets Bessie and Nicholas Higgins and there is also a scene with Mr. Thornton walking through this park.  They added some grave stones in the adaptation which were just props.
If you are ever in Edinburgh, Scotland, you will be able to walk through this park (Calton Hill) as I did with my husband, AKA the Squire, in the summer of 2009.  It looks very bleak in this photo, much as it was for the moody shots portraying the gloom of Milton/Manchester for North & South.  The structure which makes this location so recognizable is the Dugald Stewart Memorial.
If anyone knows the street that they used in Edinburgh for the Hale's house or the one used for the Higgins house, please leave a comment and let us know.  Then maybe we can find someone in or near Edinburgh to photograph it for us so we can see what it looks like without all of the Victorian props.  It probably looks quite different, unlike this view which only required a little CGI for the skyline and a few Victorian looking gravestones.

Well, Happy 200th Birthday to Mrs. Gaskell and if you haven't seen this or read the book, you must do so now.  Trust me.



Addendum: I have just had a comment from Phoebe (see below) which is directing me to the site of RichardArmitageOnline.com for their assistance, as the locations for North and South have been well researched by fans.  Yay!  Thanks for your help Phoebe.  Here is the link for those interested in the locations for North and South, including the ones in Edinburgh.
Now, any volunteers in the UK to take photos of these locations?
