The Monte-Carlo Casino is located in the principality of Monaco.  It was built in 1878 by Charles Garnier, who also built the opera house in Paris.

The Eiffel Tower (French: La Tour Eiffel, /tuʀ ɛfɛl/) is an iron tower built on the Champ de Mars beside the River Seine in Paris, France. It is one of the tallest structures in Paris and possibly one of the most recognized monuments in the world.^[1] Named after its designer, engineer Gustave Eiffel, it is the most visited monument in the world; 6,428,441 people visited the tower in 2005^[2] and more than 200,000,000 since its construction.^[3] Including the 24 m (78.7 ft) antenna, the structure is 324 m (1,063 ft) high (since 2000), which is about 81 stories. In 1902, it was struck by lightning, which meant that 100 metres of the top had to be reconstructed and the lights illuminating the tower had to be replaced, as they were damaged by the high energy of the lightning.
