The Cities above are so placed in an alphabetical order
and not by any means on an arguably competitive basis
In hindsight, having travelled to Beijing, Paris, London & New York, the four major metropolitan cities in the world, I just can’t begin to take stock as to which city I like best. I guess each one has its own unique attractions to offer and likely too because of differing love & interests, each individual will have have a different opinion.
I asked my wife for her choice of the appealing attractions of each place and she indicated the following:
Beijing
The magnificent Forbidden City is the largest & the best-preserved imperial palace complex in the world. It has 9,999 rooms during the flourishing period, just one room short of the number that ancient Chinese belief represents ‘Divine Perfection.’ It is surrounded by a moat six metres deep & a ten-feet high wall. For five centuries, this palace functioned as the administrative centre of the country.
The Great Wall of China is one of the ‘Eight Wonders of the World’ and is enlisted in the World Heritage Directory. This immense wall was built to keep out invaders as well as to retain the inhabitants. It spans five provinces from Shanhaiguan Pass in the east to Jiayuguan Pass in the west, looking like a gigantic dragon across deserts, grasslands and mountains. In the downtown area of Beijing, it is possible to climb Badaling Great Wall.
The solemn and respectful Tiananmen Square is the largest central city square in the world, which serves not only Beijing’s symbol but also the whole of China. This immense courtyard is surrounded by a variety of significant edifices such as the Tiananmen Tower, Great Hall of the People, Mao Zedong Memorial Hall, Monument to the People’s Heroes and National Museum of China.
Paris
Eiffel Tower
Probably the best known landmark in Europe, the Eiffel Tower is the symbol of Paris and one of the city’s must-see attractions. You can climb up the stairs or take the elevator after waiting in the (long) queue.
One of the not-to-miss sights in Paris is the Louvre Museum, possibly the most famous museum in the world with a fabulous collection. It is housed in the Louvre Palace, once home to France’s Royal Family.
The Notre Dame de Paris is one of the first Gothic Cathedrals ever built.
Construction started in 1163 and lasted for almost two decades. From the lookout at the north tower you have a great view over the city.
London
Big Ben
The Clock Tower of the Palace of Westminster, known as the Big Ben, is one of London’s most famous landmarks. At the time the tower was built in 1858 its clock was the largest in the world.
Tower Bridge
London’s Tower Bridge is one of the most recognizable bridges in the world. Despite being disliked by many when it was built in 1894 the bridge soon became one of the London’s most famous landmarks.
Piccadilly Square
Piccadilly Circus is a busy square in the heart of London. It is famous for the fountain that was installed here at the end of the 19th century and for the neon advertising that turned the square into a miniature version of Times Square or Beijing’s Tiananmen Square.
New York
Empire State Building
Tired of staring up at New York City skyscrapers? Check out the view of New York City from atop the Empire State Building. The Empire State Building is a classic New York City attraction, and offers visitors wonderful views of New York City and the surrounding area.
Statue of Liberty” The Statue of Liberty was a gift to the United States in honor of the friendship established during the French Revolution. The Statue of Liberty has become an American symbol of freedom and welcome to the immigrants who come to the USA looking for a better life. While the interior of the Statue of Liberty is closed for improvements, you can still visit Liberty Island and nearby Ellis Island.
Grand Central Terminal Renovations since its opening in 1913 have turned Grand Central into more than just a hub for transportation — there are shops, dining and more available to visitors. Grand Central is both an essential transit hub and a beautiful example of Beaux-Arts architecture.

Dear Paul.
How lucky we are that we have visited those cities ourselves.
Not that we are ingrates, but we are still more impressed with the Great Wall and The Ten Tombs. But at the same time shudder to imagine how many lives died because of them.
