Math treasure hunt
Details: Louvre visit
The world's largest art museum, the Louvre is housed in a Medieval fortress-turned-castle so grand it's worth a tour itself. You walk through the 71-foot glass pyramid designed by I.M. Pei and added in 1989, and step into another world--one with carved ceilings, deep-set windows, and so many architectural details you could spend a week just admiring the rooms. The Mona Lisa is here, as well as the Venus de Milo and Winged Victory (the headless statue, circa 200 BC, discovered at Samothrace). The Louvre has seven different departments of paintings, prints, drawings, sculptures and antiquities. Don't miss the Egyptian collection, complete with creepy sarcophagi, or the collection of Greek ceramics, one of the largest in the world. (Please note the Louvre is closed on Tuesdays.)
Details: Paris Sewer Museum visit
The curious have been touring the Paris sewers since the 1850’s. Visit what Victor Hugo called the Paris below Paris, “…a Paris of sewers; which has its streets, its crossings, its squares, its blind alleys, its arteries, and its circulation, which is slime, minus the human form." Experience the Paris Sewers Museum, which is located beneath the Quai d’Orsay on the Left Bank, is a popular destination for anyone interested in how a major metropolitan city manages its waste and water recycling.
Details: Seine River cruise
See the city from the water on an hour-long cruise along the River Seine. The Seine cuts right through Paris, dividing the city in half. See the Eiffel tower rising up on the Left Bank, the walls of the Louvre on the Right Bank. A guide will point out other monuments and architectural marvels as you pass, many of which are illuminated by clear white light at night.
