Mosteiro da Serra do Pilar

This monastery is the symbol of the city of Vila Nova de Gaia , and although I had the opportunity to visit inside, it does not go unnoticed because it is on top of a hill and is visible from any point, especially since the Muelle de la Ribera Port is just opposite. The entire area of ​​the bank of the Douro is considered a UNESCO World Heritage Site. It was founded in the 16th century by the Augustinians. What is surprising is the church with a circular dome, a replica of the Church of Santa Maria Round of Rome.It was a defensive fortress-like monastery, and in fact was used as such in the year 1832.
