Lots of buildings have statues on them but they seldom get noticed because they are part of the background. They are worth looking at not just because of their artistic merit but because of the message they they may be trying to convey. The people who built the building or its original owners(usually) had statues put on the building to convey a message about themselves usually in the form of some sort of allegory. This means when you look at statues you can play guess the meaning. Sometimes you need to know christian mythology (guess the saint) or the classics (guess the Ancient Greek/Roman Legend). I am not much good at either. Todays photos are statues on the Mercat building at Glasgow cross and are mostly obvious what they represent. They are also very much in the style of when they were created (late 1920s).
