Porto, as I've personally photographed and documented.

Porto is a place where I always make sure to take photos and keep records when I travel. Especially because of the Dom Luís I Bridge, it seems like a great spot to capture the view from above to below, which is why I have memories of beautifully documented nooks and crannies. The city is so small that you can get anywhere by taxi for about 4-5 euros, but the atmosphere the bridge provides makes it feel truly majestic.
