Travel in China – the Great Wall | watch tower

During our “ascent” to the highest point of the section, we stopped at one of the watch towers to catch our breath,..well, umm, to take some pictures. Here you can see 2 rectangular blocks at the top of the structure. If you take a look at the first picture, you will notice there are 5 rectangular blocks on each side of the watch tower. This ought to give you a sense of scale how big the structure is.
