The most famous landmark in Paris was nearly torn down in 1909 as some opinions labelled it an eyesore. Arcitect Gustave Eiffel built it for the 1889 Expo held in Paris to show off the quality of French steel. 10,100 tonnes of iron went into the 324m structure. You can choose to climb the 1710 steps to the top (€3.80 to level 2) or if you arrive early before 9.00am to beat the hordes you can take the lift. Another alternative is to take a late evening cruise down the Seine to watch the light show. 20,000 flashes were installed for the Millennium celebrations and return occasionally adding to the city of lights reputation. Various lighting displays illuminate the sky every year. Prices depend on how high you want to go, €4.20 to the first level, €7.70 to the second and €11 to the top. Open every day, Jan 1-June 15 and Sep 3-Dec 31, 9.30am-11.45pm, June 16-Sep 2, 9am-12.45am .
