Apparantly, the Danvers State hospital site is the original site of the Salem Witch Trials, where they hung the accused. Might just be an urban legend though, however it is quite near where Salem is today…

Not an urban legend! The majority of activity concerning the witch trials took place not in Salem proper, but in Salem Village, which later was called - yep - Danvers.

And while non one is exactly sure on this, they believe that some of the condemned were hung on the hill where Danvers Hospital stands today.

Small wonder H.P. Lovecraft mentione dit in so many stories.
