Monte do Tadeu – is the highest area in Porto. It exist since the 17th century. And I live here now.. in 21th. Every morning right from my window I see this old water tower. And it is so beautiful that I could not stop myself for climb it.
The water tower on Mount Tadeu was the main source of water supply for Porto from 1887 to 1927. After it also worked, but not as the main source. Now this place is under reconstruction, closed and guarded. There is water inside these structures. If you climb to the top of the tower (what is impossible, the place is closed completely), then you can see the ocean and all city.
If you are familiar with Geocaching, then in addition to a walk to the highest point of Porto, you can try to find a cash here. I found it only from the third time, it was really crazy: it’s all so simple, but I could not find it at once, I could not sleep at night until I found it)). Try it – maybe you will get better.
