Dog barks continuously at passers by when at second home

I have a 2 year old dog who when at home in the city he has no problems, he’s crate trained and and he’s calm 99% of the time.

The issue is that now that it’s Easter (orthodox) I took him to my village (about 2000 people) and he goes crazy all night long if he hears anyone walking by the house and keeps the neighbours up too…

Is there any idea how I can train him to keep calm during the night because in the city he doesn’t react to noises but here it drives him crazy?

edit: he’s a lab mix with Greek Shepard (about 33kg) if that helps
