The protocol will defend on the country and specific location where you want to display the flag. You may need to make a request from local govt officials.
Unless it is American soil, like at an Embassy, you don’t typically see American flags flown in Europe.
As for parades and ceremonies, you may be able to get temporary permission for that event, lasting only for that day.

I would like to know the protocol of displaying the American Flag in Europe.

I am on the board of an association which regularly represents the United States of America at ceremonies such as veteran’s day and for the liberation of Europe etc.

Can you point me in the right direction to help me understand how to do this right.

Thank you very much.

That’s very cool, thanks for visiting me! I can tell you that in Rota, Spain, there is a small Thrift Shop on base run by the Navy. But the good deals come from the local weekly flea markets called Gypsy markets. And the great antique finds are at the Sunday market in Cadiz. 🙂

Thanks
