The real entrance to Venice is, as you might have guessed, under water in the Adriatic Sea. Somehow you can see it clearly in spite of the murky ocean that surrounds the city. You just have to open your eyes. It’s one of those things where you just need to be in the right place at the right time. Everything from this vantage point at the entrance has an other worldly, perspective-defying, dreamlike character. Oh, and everything is turquoise. Così è la vita. (Such is life).
