Image: The Eiffel Tower is worth EUR434bn to Paris

The Monza and Brianza Chamber of Commerce in Italy has revealed that the Eiffel Tower is Europe's "most valuable" monument - worth EUR434bn (US$544bn, £342bn) to Paris.

In the research, the organisation found the value and brand of the landmark tower was worth one and a half more to the French capital than fashion, panettone and San Siro is to Milan.

The brand "value" of European monuments and attractions was measured using 10 primary parameters - such as the economic value of land; visitor numbers; and a site's reputation.

La Sagrada Familia is worth an estimated EUR90bn (US$113bn, £71bn) to Barcelona, Spain, while the Tower of London is worth EUR70bn (US$88bn, £55bn) to London, UK.

Other landmarks included in the study included Stonehenge, UK, and the Museo del Prado in Madrid, Spain. Economic appeal such as the numbers of job and accessibility were also considered.
