Mysteries – Do you know?

OK this is my week for asking my readers questions. I am posting a few pictures that have me scratching my head. One is of a tile depicting a saint – well, he has a halo! He seems to have a falcon on his hand as he rides his horse. Any idea who he is? Then there is a weird rock formation. The picture was taken looking at a cliff face. Obviously water has worn a channel down the rock but I wonder why it is that pink color. Next is a lovely plant that is blooming everywhere.  Is it Mimosa? Finally, this machine on the beach had me puzzled. I presume it is to haul boats up the beach but ….is that a car engine? Curiouer and curiouser as Alice would say!
