1 Best Sight in Denver, Colorado

This 330-foot-high, 20-floor structure emulates the Campanile of St. Mark's Square in Venice, and it was the tallest building west of the Mississippi when it was built in 1909. William Cooke Daniels originally commissioned the tower to stand adjacent to his five-story department store. Today it's an office building with a cabaret in the basement as well as the city's most convenient clock tower. It's particularly striking—the clock is 16 feet high—when viewed in concert with the fountains in the adjacent Skyline Park.
