Holy Water

Every once in a while, I take a picture that I really like. This one was taken at a lake in Yufuin (in Oita-ken), and I had to venture out into the water to get it.
I really like the shrines that are built in or around water in its various forms. They seem more powerful, or at least more interesting. This one made me wonder: did they drain the lake in order to set the concrete columns in place and then fill it back up, or did they build it and then create the lake, or did they just sink in the columns pre-fabricated? Of course, it would be cool if it just magically appeared from the void or if it was built by supernatural beings, but if this were the case, I would hope that they would use more exotic building materials, like an all knowing oracular slab of midnight blue sapphire that could only be awakened by the one who was foretold of by the prophecy, or a rock that would be indistinguishable from ordinary concrete, that if touched would instantly cause its victim to be disintegrated, transomgrafied, or transported to a different dimension.
