Here is a very detailed baroque pin from the mid to late 1800's- most likely a collectible souvenir perhaps from a Grand Tour of Europe.
At first I was not sure what the tiny hand-painted scene was. It looked like a type of church. The colors are very pretty, and while searching with a loupe, I saw the tiny words Kloster Andechs.
Kloster is German for monastery, and this one is known for it's Baroque church and it's brewery.
