This site is on the List of Pennsylvania state historical markers in Allegheny County. Fictional Portrayals The Square serves as the backdrop to revealing scenes in the 2002 thriller The Mothman Prophecies with Richard Gere and Laura Linney. In the movie Gere travels to "Chicago" and meets "The Professor" in the square. Many Pittsburgh landmark buildings and cathedrals are showcased and get close-ups to add a visual layer to the revelations discussed in the square. Renovation The Pittsburgh Parks Conservancy along with funding from the Richard King Mellon Foundation, The Colcom Foundation, The Eden Hall Foundation, BNY Mellon and other, spent $10 million and many years to renovate the square. The project replaced all of the original flooring and stairs, which had fallen into disrepair. The square re-opened to the public in May 2014. Trivia The square opened with over 25,000 trees, shrubs and flowers. The nine circular bronze basins for the block-long fountain were in 1953 the largest ever cast. The Union Square underground garage in San Francisco served as inspiration for the facility and square.
