One of the day trips we took was a cruise to Heart Island, to visit Boldt Castle. This was built as a hunting lodge, or rather I'm guessing as holiday home, for the Boldt family. The Castle has 120 rooms, in 6 stories, fancy gardens, it's own power generation building, a dove-cote and even a playhouse. In 1904, the lady of the household died unexpectedly and all building was stopped, leaving it unfinished and never used. It's being restored to what would have been it's former glory if it had been finished. I didn't take photos of the inside as there were just too many people around. Only a portion of the castle has been restored, but much of the rest was open to the public. You could see many of the original materials. As well, there were copies of the original plans, so they know what it was supposed to look like.
There was so much to see and so many renovations still happening that we'd love to go back in a couple of years to see how it's progressed.
