The Eiffel Tower in Paris is the most valuable monument in Europe, worth some €434 billion, according to a new study.

Paris' iconic skyline feature is estimated to be worth six times the Colloseum in Rome, according to study published by the Chamber of Commerce of Monza and Brianza in northern Italy.

The study has compared and assessed the financial value of various historical European monuments, according to a report in the Lavieimmo.com website. The study is based not on any material value, but on image, branding and aesthetic qualities.

What's more the value of the tower, nicknamed the Iron Lady and erected in 1889 as the entrance arch to the World Fair, is the equivalent of 25 percent of France's GDP or almost the entire capacity of the European Financial Stability Fund.

The Eiffel Tower comes out top in the rankings, followed by the Colloseum in Rome, estimated to worth some €91 billion, and Gaudi's unfinished cathedral masterpiece La Sagrada Familia in Barcelona at €90 billion.

Other celebrated monuments in the list include the Dome of Milan, worth some €82 billion, the Tower of London at €70.5 billion, The Prado museum in central Madrid at €59 billion,  and Stonehenge in western England worth €10.5 billion.

According to the study Europe's leading monuments are worth a total of €700 billion. 

The Italian study also put a price on the White House in Washington DC - some €81 billion.

The study has been compiled using the Eurostat business register.
