The Congress Plaza Hotel is located on South Michigan Avenue across from Grant Park in Chicago at 520 South Michigan Avenue. After opening for business in 1893, for the World's Columbian Exposition, the hotel underwent two major expansions and renovations; it now features 871 guest rooms and suites. Its 11 story edifice was originally designed by architect Clinton J. Warren as an annex to the Auditorium Theater across the street. The two buildings were linked by a marble-lined underground passage called Peacock Alley. In 1902 and then in 1907, the firm of Holabird & Roche oversaw the design and construction of two additions, bringing the total complex up to 1 million square feet.
In June, 1912, Theodore Roosevelt stayed at the Congress Plaza when the 1912 Republican National Convention was held in Chicago. Roosevelt, who at that time was seeking the Republican nomination for President, spoke from the balcony of his room at the hotel to a crowd assembled across the street in Grant Park.
In October 1916, US President Woodrow Wilson passed the hotel as part of his visit to the city. Over a hundred protestors from the National Women's Party demonstrated in favor of women's suffrage with a silent protest. Holding banners such as "Wilson is Against Women," the demonstrators were attacked by a mob and their banners destroyed while police looked on and, in some cases, laughed, according to newspaper reports.
In 1940, Louis Grell (1887-1960), a Chicago-based artist, was commissioned to paint thirteen murals for the lunettes that are an architectural feature surrounding the grand lobby. The murals were various popular scenes around Chicago at the time. Under the Albert Pick Jr ownership in 1952, Grell was again commissioned to paint the same architectural lunettes, this time Grell incorporated Chicago figures into the scenes depicting important trades significant to Chicago's growth and symbolism. Lady Liberty was found in one mural holding the Chicago River "Y" on her lap. Additionally, in 1955 Pick commissioned Grell once again, during one of the many renovations, to paint three walls for the newly decorated Pompeian Room which also had a magnificent Louis Comfort Tiffany glass fountain in the center of the vast room. Today glass covers the thirteen lunettes where the murals could be hiding. Grell also painted a large white Peacock that was mounted above the bar next to Peacock Alley. Each wall had a main central Greek/Roman mural, however, Grell decorated the entire wall with various patterns of flora and custom design.
