The tower in the first photo is Sydney Tower, which is Sydney's tallest free-standing structure, and the second tallest in Australia (with the Q1 building on the Gold Coast being the tallest). It is also the second tallest observation tower in the Southern Hemisphere (after Auckland's Sky Tower, though Sydney Tower Eye's main observation deck is almost 50 m higher than that of Auckland's Sky Tower).
The name Sydney Tower has become common in daily usage, however the tower is also known as the Sydney Tower Eye, AMP Tower, Westfield Centrepoint Tower, Centrepoint Tower or just Centrepoint. The Sydney Tower is a member of the World Federation of Great Towers. The tower stands 309 m above the Sydney central business district (CBD), located on Market Street, between Pitt and Castlereagh Streets.
It is accessible from the Pitt Street Mall, and sits upon the newly refurbished Westfield Sydney (formerly centrepoint arcade). The tower is open to the public, and is one of the most prominent tourist attractions in the city, being visible from a number of vantage points throughout town and from adjoining suburbs.
The building in the centre of the park is the Anzac Memorial.
