"Lindsay's Folly", located in Rideau Park on east bank of Elbow river overlooking Elbow park, Calgary, Alberta.

We are exploring the ruins of one man's dream. It is called Lindsay's Folly, the remnants of a mansion now overrun with weeds. Neville James Lindsay was a doctor who arrived on the first passenger train into Calgary in 1883. "Which is like coming over on the Mayflower," says Harry.

Dr. Lindsay beat the odds, trekking north and striking it rich in the Klondike. When he returned, he decided to build himself a sprawling sandstone manor. He purchased Calgary's old Knox Presbyterian Church and had it destroyed, dismantling the stone blocks and bringing them here to a wooded escarpment above the Elbow River.

The history of Calgary has always been one of boom and bust, and in Lindsay's case, the boom went bust at the worst possible moment. His house was abandoned just a few months after construction began, and there it lay, looted for most of its sandstone, the proud arch long gone, and little more than its retaining wall and a crumbling concrete foundation left behind: an Ozymandias arrangement in the hidden hills of Calgary. It's as much a parable as it is a historic site.

"An early example of the dangers of doctors investing in real estate," says Harry.
