The 0.68€ stamp on the left is from 2010 Public Elevators of Portugal issue depicting "Santuario do Bom Jesus do Monte" Elevator in Braga.
The city is also known as the "Portuguese Rome" for its concentration of religious architecture. Braga is located in the North of Portugal, the more developed territory. This town is the commercial and business center of the region.
In Portugal, Braga's population is considered the most conservative, and by some the most pious, by others the most fanatic. The city is one of the most beautiful cities in Portugal.
Not far from the city center there are three important sanctuaries: "Bom Jesus","Sameiro" and "Santa Marta da Falperra".
The 0.32€ stamp is from 2010 Circus Chapito issue. I found some information here.(in Portugese)
