The ruins of the Alexander Goddard mansion are at Ft. Williams state park, the same place as the Portland head light. It is a huge old shell of a building completed in 1857. The house was damaged by fire several times and part of it was destroyed in a controlled burn in 1981.
This was taken the same foggy day I took the photo of the Portland head light I posted earlier so its rather flat... but its an interesting place.
