The image below is of a quite inventive sundial to be found in Jardim Botânico, Rio de Janeiro, Brazil. Here is a web page with more photos of it, but you’d have to speak Brazillian to understand the rest.
So, let’s have a look at a few more. This one can be found at the Gyeongbokgung Palace, in Seoul, South Korea.
There is also a category of wall sundials. These are quite prolific throughout Europe and can be seen on old building such as churches and municipal buildings. This one can be found at St Lawrence, the Eyam Parish church, Derby, UK.
Of course, the great thing about sundials is that they don’t have to be elaborate. Here is a “sunwatch” pocket sundial.
Oh, and just kidding about Brazillian. I know they speak Portuguese in Brazil.
