The Eiffel Tower is an icon of modern France . Standing 324 metres tall, it's the tallest building in Paris and the fifth tallest in the world. Today, the Eiffel Tower is a tourist hotspot and visitors can climb or use the lifts to reach the first or second floors, the latter of which is 115 metres high. The most expansive views can be found on the Eiffel Tower's third level at 276 metres, which has its own separate lift from the second floor. A backstage tour is available, which details the workings of the Eiffel Tower and its history.
Pont du Gard is an iconic Ancient Roman bridge and aqueduct built in first century AD located near Nimes in France. It was the tallest bridge ever built by the Romans, rising 160 feet. Nimes had been a major city of Gaul before 45BC, when it was incorporated in the Roman Empire. As the city's population grew, exceeding 20,000, the need for water surpassed the available supplies of the Nemausus spring. Thus from 40AD over 1,000 workers were engaged in building Pont du Gard in order to transfer water from the Gard River to the city.
