Funny little detail about the buildings at the top of Ridgewood Ave in Cote des Neiges: when they were built, in 1955-1956, they were designed to form the shape of a cross from above.So, in fact, there are actually about a dozen crosses on Mount Royal, not counting the cemeteries.
Another weird little detail: on at least one of those buildings near the top of the hill, one corner of the foundation is a 63-foot column.
The column - stuck into a lower portion of the mountain - supports a massive 63 ft by 144 foot slab of concrete. So the basement-parking lot upon which at least one of those buildings is constructed is actually well above the ground.
