OK sleuths. Where in the world is this building? This structure, over 700 feet tall, was for a time, the tallest building in the world. Rumored to be a future Marriott Hotel or associated brand property (denied by Marriott as of today, by the way) in an icon of this city. Another hint: it was built to resemble a famous structure in Venice. (thus it's not there). It was built in 1905.
