Throughout 2013, several events celebrated the 100th anniversary of the naming of Canberra. On 11 March 2014, the last day of the centennial year, the Canberra Centenary Column was unveiled in City Hill.  Other works included ''The Skywhale'', a hot air balloon designed by the sculptor Patricia Piccinini, and ''StellrScope'' by visual media artist Eleanor Gates-Stuart. On 7 February 2021, ''The Skywhale'' was joined by ''Skywhalepapa'' to create a ''Skywhale family'', an event marked by Skywhale-themed pastries and beer produced by local companies as well as an art pop song entitled "We are the Skywhales".
