Thanks for putting me at ease. For the record this castle(?) is located on the shore of Gloucester Harbor in Massachusettes, USA. There are a number of examples of unique architecture around Gloucester which seems to have attracted some wealthy eccentrics in the early 1900's. The most famous would be the Hammond Castle built by the organ manufacturer and now open as a museum. The castle in this photo appears empty.. maybe for sale? The sky photo was taken over Block I. Sound on Oct 21 just a few days after the castle photo. Thanks all for looking.
