La Antigua Guatemala has many window corners like this one, a window that opens to the view of both streets. Also, another architectonic element all over Antigua are the domes or cupolas; you can see two sticking out above the roof.

In fact that is not an usual corner, welcome from Porto and keep showing us your happy Antigua Guatemala!
Thanks for the visit. Maybe this corner is not unusual to latin countries. But for sure it is not common in other parts of the world.
