Well, to me at least.
In Portugal you’ll find lots of more or less strange monuments (many of them religious) in more or less strange places.
Here you can see part of the Bom Jesus das Mós, a small religious monument I came across with in Gerês. It was built between 1902 and 1912 and, from the top, you get a great view of the surrounding area.
Above all I think this monument caught my eye because it was built with the boulders as part of its structure (following a common characteristic found in houses in the region) but also because of the way the stairs were built: you have one common entrance, you can turn left or right on the next level but, in the end, to get to the top, there’s only one entrance as well.
