Other works and events were experienced at various locations throughout the city, including Henrik Håkansson’s epic, episodic film and orchestral performance work, THE END (2011), which was presented at Pier 2/3 in Walsh Bay. In 2014, more than 623,000 visited the Biennale partner venues, including close to 125,000 from overseas, the highest international visitation numbers recorded in the Biennale’s 41-year history. In addition, audiences also experienced outdoor works by Nathan Coley on the Eastern Apron of Cockatoo Island, and the building exteriors of the Art Gallery of New South Wales and Museum of Contemporary Art Australia, as well as numerous performance works in public spaces.
