Wrigley Building

The Wrigley building serves as the headquarters of the Wrigley (chewing gum) company and was built in 1920 by the company's founder, William Wrigley Jr.

The construction of the Michigan Avenue Bridge and the widening of Michigan Avenue opened up a wide boulevard across the Chicago River to the north. In 1918, William Wrigley, Jr., sensing the potential of these developments purchased a plot of land near the bridge to build the city's first landmark skyscraper north of the Chicago River.
It was the first of a series of landmarks at the southern end of what would later become the Magnificent Mile: its famous neighbors are the Tribune Tower (1925), the 333 North Michigan Avenue (1928) and the London Guarantee Building (1923). The Wrigley building stands out with its sparkling white terra-cotta cladding, the well-proportioned architecture and the nighttime floodlighting.

The Wrigley building was modeled on the Giralda tower of the cathedral in Sevilla. It consists of 2 sections: the tallest, 27 story southern building has a 121 meter high tower (398 ft) and was completed in 1921. The largest, 21 story northern section was completed in 1924 and reaches a height of about 90m (294ft).
The 2 structures are connected by an open walkway on street level and 2 elevated walkways on the 3rd and 14th story.

Between the two structures is the small Wrigley plaza. It was originally designed by the Wrigley building's architects, Graham, Anderson and Probst, but wasn't built until 1957 by Louis Solomon and John Cordwell.
