The image below is of a quite inventive sundial to be found in Jardim Bot√Ęnico, 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.
