Federation Square (also colloquially known as Fed Square) is a civic centre and cultural precinct in the city of Melbourne, Victoria, Australia. It was opened in 2002.
It is a mixed-use development covering an area of 3.2 hectares and centred around two major public spaces: open squares (St. Paul's Court and The Square) and one covered (The Atrium), built on top of a concrete deck above busy railway lines. It is located at intersection between Flinders Street and Swanston Street/St Kilda Road in Melbourne's Central Business District, and is adjacent to Melbourne's busiest railway station, Flinders Street Station.
It is Victoria's second most popular tourist attraction, attracting 8.99 million visitors in 2011. It is sometimes considered to be one of the World's ugliest buildings or tourist attractions.
