Italian Souvenir

I wanted to leave an "Italian" memory for the participants, almost all of whom came from abroad, so I chose some famous monuments and created a container to fit them together.

As always in this type of puzzle, the pieces should not protrude or overlap. It's probably not very easy to solve. As far as I know, no one has found the solution yet.

I ship from Italy all over the World. You will choose the courier / shipping methods and you are responsible for custom duties.
You can buy more puzzles and save on shipping costs, with a single parcel. For any questions and to allow me to check the shipping costs, please ask before bidding.
