It looks a bit like this tree is growing out of this little green shack, but unfortunately, that’s not the case. I’m not exactly sure what this shack is used for, but it looks like it’s in desperate need of repairs. Someone did once go to the trouble of painting the chimney bricks the same colour as the shack though.

These are just two green doors that I found in the park. I think the one on the left is a bathroom — the one on the left is a mystery.

This is Casa Loma in Toronto. It has 98 rooms, and actually used to be the largest private residence in North America. If you’ve ever seen the movie X-Men, then you’ve seen the interior of Casa Loma before — it was used as the inside of Charles Xavier’s (also known as Professor X) School for Gifted Youngsters (the X-Mansion).

OK, so it’s not really the end of the Great Wall. It’s just a place where the natural rock was so steep that the builders didn’t need to build the wall any higher — so it stops rather abruptly at the rock’s edge.

One thing that struck me about the Great Wall was that I couldn’t understand how anyone could possibly cross those mountains on foot or horseback. It just seemed impossible.
