The Sydney Opera House, an iconic building in Australia.

Ever since the architect Ding Utterson created her elegant swan-like form with natural lines, the Sydney Opera House has been one of the most famous opera houses in Australia and the world.

The Sydney Opera House has been one of the most famous opera houses in Australia, and in the world, ever since architect Ding Utterson outlined its elegant swan-like shape with natural and smooth lines.

What is not known to the world is that the designer, Utterson, resigned from Australia after a quarrel with the state government over the modification of the design due to the construction funds.

He never revisited the continent and has yet to see the architectural wonder of his own design in person.

The Sydney Opera House stands on Benilan Point in Sydney, the capital city of New South Wales.

It is located on a small peninsula next to the world-famous Harbour Bridge, surrounded by the sea on three sides.r

The architecture is novel and strange.

The shape of the building is like a group of ships sailing out to sea.

It is also like a large white shell standing on the beach, which is poetically integrated with the surrounding sea scenery.

The Sydney Opera House was inaugurated in October 1973, after 14 years and over $100 million in construction.

Queen Elizabeth II made a special trip to cut the ribbon.

The Sydney Opera House building has a total area of 88,258 square meters, and the entire building covers 1.84 hectares, which is equivalent to the height of a 20-story building.

It is built on a very high concrete platform.

The large steps in front of the entrance are 90 meters wide and paved with peach granite.

It is said to be the largest and longest outdoor concrete staircase in the world today.

The exterior of the Sydney Opera House consists of three sets of giant shells standing on a cast-in-place reinforced concrete structure with a length of 186 meters from north to south and a maximum width of 97 meters from east to west.

The first group of shells is on the west side of the lot, with four pairs of shells arranged in a series.

Three pairs facing north and one pair facing south, with a large concert hall inside.

The second group is on the east side of the lot, roughly parallel to the first group, with the same form but slightly smaller scale, and the interior is an opera hall.

The third group, to the southwest of them, is the smallest, consisting of two pairs of shells and containing the dining room.

The other rooms are cleverly arranged within the plinth. The entrance to the entire complex is at the southern end, with a 97-meter-wide grand staircase.

The vehicle entrance and parking lot are located underneath the steps.

The Sydney Opera House is a successful building for music and theater performances with excellent facilities and effects.

Those huge white shells near the water are like sails on the sea, and like a cluster of flowers in full bloom.

This building has been regarded as the world's classic architecture in the history books.
