Built by Gustave Eiffel for the 1889 World's Fair to commemorate the centennial of the French Revolution, the Eiffel Tower is now one of the world's most recognisable monuments as well as one of the most visited ones, attracting nearly seven million visitors every year. It towers over the city at 324 metres (1,063 feet) and weighs over 10,000 tons, making it both an imposing monument and an engineering marvel. Climb all the way to the top for a breathtaking view of the City of Light.

An embodiment of the iconic Greek white-with-a-blue-dome, postcard-ready look that dominates postcards, this structure is set atop a high hill and dates back to the 18th century.

Downtown (El Centro) is the actual backbone of Cancún. What it lacks in history, it makes up for being a true melting pot — an exciting mix of the old traditional Mexico and an ultra-modern urban sprawl. Avenida Tulum, the main street, passing through the heart of the city, is easy to reach by public transport. The street is lined with shops, cafés, bars, and restaurants. Be sure to stop by Parque de las Palapas, on the market square, where locals come to chat and watch the entertainment provided by various local groups. The lively atmosphere and the sound of Mexican music are infectious, and any worries will quickly be postponed to "mañana." Browse around the artisan stalls and try some of the local sweet delicacies or visit the "Hippie Market" around the corner. In the evenings, the place to be is Avenida Yaxchillan with its lively restaurants and bars, popular with locals and tourists alike.

The historical Centralia Union Depot was built in 1912 as a transportation center, gathering place and landmark. All original exterior and interior structure is still maintained: the red bricks, woodwork, tiling, and oak benches remain. Today the Union Depot is served by Amtrak, acting a midpoint between Kelso and Olympia.
