Those used with Italian coins certainly know the 1 Eurocent piece.
On the coin there is an artistic reproduction, but ...
... if you travel to the Andria municipality (Puglia Region) you can see the original one.
It was built on the top of a hill by Emperor Frederick II in the 13th century.
You can enjoy a panoramic view before entering the castle, which has ...
... an octagon shape reproduced in the sky's view that you can see if you raise your head upwards when you are in the internal courtyard.
There are many rooms to visit in the interior.
It is a hiking the past.
It needed a bit of luck to take a picture of the internal courtyard without people.
The view from the castle dominates the landscapes around it.
