In parts of Colombia - we particularly noticed them in Cartagena and in Barichara near San Gil - some of the door knockers in the central part of town are really quite elaborate.
On a walking tour with Kristy from Cartagena Connections, we learnt that (originally at least) the shape of the knocker could tell you something about the house's occupants.
For example, lizards - which are particularly frequent - are symbols of the aristocracy, as the animal is associated with having blue blood.
There are also quite a lot of different types of fish, suggesting links with the fishing industry.
They were all really quite impressive and I couldn't resist having a little knock with the turtle, which was my favourite.
