Abbadia Mare

John Hays Hammond built the house of his dreams near Gloucester MA and named it Abbadia Mare (Wikipedia). He was wealthy enough to build the castle exactly to his specs and without any constraints. He was a  bit weird, too. Among other things he displayed the skull of one of Christopher Columbus mariners and had the whole wall built of ancient Roman tombstones. He was an inventor, that’s where his wealth came from, and he made sure his house didn’t lack in gadgets. He could completely control the climate inside it via a well-concealed system of pipes and light bulbs. He could have rain, even a downpour, or mid-summer light and heat – any time of the year. For the occasions when he felt like listening to powerful music he added an eight-story organ.

The house is believed to be haunted. Did Mr. Hammond find a way to communicate from his eternal place? Or was he lost in some secret hallway and couldn’t find his way out? Or maybe, the voices which sometimes can be heard are just one more of his tricks, the one for which a secret pipe yet needs to be found.
