The Pont Alexandre III spans the Seine and connects the Champs-Elysees quarter with those of the Invalides and Eiffel Tower. The bridge is widely regarded as the most ornate, extravagant bridge in the city. Les Invalides is a complex of buildings relating to the military history of France, including a retirement home for war veterans (the building's original purpose), and the Royal Chapel, the tallest church in Paris, which houses the tomb of Napoleon.
