the Burnham Pavilions were public s

the Burnham Pavilions were public sculptures by Zaha Hadid and Ben van Berkel in Millennium Park, which were located in the Loop community area of Chicago, Illinois. Both pavilions were located in the Chase Promenade South. Their purpose was to commemorate the 100th anniversary of Daniel Burnham’s Plan of Chicago,[1] and symbolize the city's continued pursuit of the Plan's architectural vision with contemporary architecture and planning.[2] The sculptures were privately funded and reside in Millennium Park.[1] The pavilions were designed to be temporary structures.[3]
Both Pavilions were scheduled to be unveiled on June 19, 2009. However, the Pavilion by Hadid endured construction delays and a construction team change, which led to nationwide coverage of the delay in publications such as The New York Times and The Wall Street Journal. Only its skeleton was availed to the public on the scheduled date, and the work was completed and unveiled on August 4, 2009. The van Berkel pavilion endured a temporary closure due to unanticipated wear and tear from August 10–14.[4]
