Approaching the dock we pass the Power House, this was the original building that housed all of the islands utilities.

Boldt Castle, on Heart Island, was to be the testimony of the unsurpassed love of a man for his wife.  The magnificence of the structure was to be equalled only by George Boldt's adoration of Louise, who was the love of his life and reason for the construction of such an elaborate summer home.  The finest of artists, craftsmen and materials where sought for the work which was well on the way when tragedy struck.  Mrs Boldt was dead, and a telegram arrived ordering all work to stop.  Three hundred workmen dropped all their tools and left the island, never to return.   The castle remained empty from 1904 to 1977, when the Thousand Islands Bridge Authority assumed control.

On our left was the Yacht House, this entire structure housed the yachts, crews and maintenance staff.  This is located on a separate island and tours are available.
