Postcard from Portugal!

Today I got a nice postcard from Portugal! The postcard shows a traditional Portuguese windmill. These windmills are unique because they are sounding windmills. They feature earthenware vessels that produce different sounds depending on the strength of the wind and the type of weather. These are primarily used for aesthetic purposes but are also used to notify the miller of any changes in wind or weather. The postcard is an official Postcrossing card, PT-366107. Thanks Rita!
