As David reported here last week, the Danvers State Hospital is one of several former asylums currently being transformed into condos.

The next best thing to jetting off to MA in full urban exploring gear before "the world's scariest building" becomes 497 luxury homes (to what I can only presume will be Boston's most adventurous goth yuppies,) is Danvers State Insane Asylum dot com. The very well done website includes historical and up to the minute information about the site, as well as photo galleries.
