Where is Tate Modern Located in London?

Where is Tate Modern Modern located I have asked myself while standing in front of the Tate Britain?!
My pocket guide was referring only to Tate Gallery and brougt me to Millbanks.
I was kid in the fog until I turned back to internet and discovered there are 4 Tate Galleries.  So this post is solely for those who search the way to Tate Modern.

Visiting Tate Britain is was also great - there will be separate post about it.
