Sydney's Harbour - Austrália

 Port Jackson, most commonly known as Sydney's Harbour, is regarded as one of the most beautiful natural harbours in the world, around which Sydney was built. I had no idea it's official name was Port Jackson.

It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. - in: wikipedia

Sydney Harbour is famed for its sparkling waters, iconic sights, spectacular events and hundreds of kilometres of shoreline. Sydney Harbour is also a working harbour with a thriving maritime industry that supports the city’s economic development.
Australia’s busiest waterway, Sydney Harbour sees thousands of recreational, passenger and working vessels share the water with around 1,200 large commercial vessels each year, including the cruise ships that call into Sydney’s two cruise terminals: the Overseas Passenger Terminal and White Bay Cruise Terminal.
At the heart of Sydney Harbour is Glebe Island, a working port for over 100 years that today provides Sydney with a vital maritime supply route for construction materials that will build the city’s future. - in: https://www.portauthoritynsw.com.au

Construction of Sydney's Harbour Bridge in the 1930's. 

The Sydney Harbour Bridge is one of Australia's most well known and photographed landmarks. It is the world's largest (but not the longest) steel arch bridge with the top of the bridge standing 134 metres above the harbour. It is fondly known by the locals as the 'Coathanger' because of its arch-based design.

It was as early as 1815 that Francis Greenway proposed building a bridge from the northern to the southern shore of the harbour.

It took some time for this to become a reality with design submissions invited in 1900. All the submissions were considered unsuitable and so the momentum for the bridge crossing stopped.

However, after the First World War more serious plans were made, with a general design for the Sydney Harbour Bridge prepared by Dr J J C Bradfield and officers of the NSW Department of Public Works. The New South Wales Government then invited worldwide tenders for the construction of the Bridge in 1922 and the contract was let to English firm Dorman Long and Co of Middlesbrough.

The Sydney Harbour Bridge construction started in 1924 and took 1,400 men eight years to build at a cost of 4.2 million. Six million hand driven rivets and 53,000 tonnes of steel were used in its construction. It now carries eight traffic lanes and two rail lines, one in each direction, but at the time of its construction the two eastern lanes were tram tracks. They were converted to road traffic when Sydney closed down its tram system in the 1950s. - in: http://www.australia.gov.au
