"It's funny, we were trying to figure out how the Sword Coast should look, and one of our artists said we should go do some photogrammetry along the coast of Portugal, as he thought it’d be a good fit. But as he was doing his research, he looked at the emblems of one of the Portuguese cities and it was the same as the emblem you find in the books for Baldur’s Gate. He actually accidentally discovered where the Sword Coast was in the real world. So for the game we just scanned the real-life Sword Coast!"
I've done some research and found nothing. Do you guys have any idea of which part of Portugal is he talking about? Also which emblem?
