In what year was construction of the Eiffel Tower completed?

Question: What year was the Eiffel Tower in Paris built?

Answer: Construction of the Eiffel Tower in Paris, France began in 1887 and was completed in 1889 with it officially opening on the 1st of March that year.

When the tower was first built, Gustave Eiffel only had a permit allowing the tower to stay in place for 20 years, after which it was due to be dismantled.

However due to the 324 meter high tower having become important for radio broadcasting and communications, the City of Paris which now owned it chose to keep it standing. This decision later proved to be a very important one.

A few years later after the outbreak of World War One, transmitters were fitted to the tower designed to block German communications which proved successful, becoming a key factor in the wars outcome.
