Drone’s eye photography of the church of the Leça do Balio Monastery. The monastery dates back at least to the year 1003 but this church was built between 1330 and 1336. At the base of the tower there are some anthropomorphic grave stones that where dugout during renovations. You can see the original on Flickr.
Drone’s eye view of Crestuma-Lever Dam with the flood gates open. The Crestuma-Lever Dam on the river Douro creates the reservoir for water supply to the city of Porto. You can see the original on Flickr, I also contributed the photo to Wikipedia.
