Query: In what year was the Eureka Tower completed?
Context: In 2012, the city contained a total of 594 high-rise buildings, with 8 under construction, 71 planned and 39 at proposal stage making the city's skyline the second largest in Australia. The CBD is dominated by modern office buildings including the Rialto Towers (1986), built on the site of several grand classical Victorian buildings, two of which — the Rialto Building (1889) designed by William Pitt and the Winfield Building (1890) designed by Charles D'Ebro and Richard Speight — still remain today and more recently hi-rise apartment buildings including Eureka Tower (2006), which is listed as the 13th tallest residential building in the world in January 2014.
