In what year did the Suez Canal open?

On November 17, 1869, the Suez Canal was opened to navigation. Ferdinand de Lesseps would later attempt, unsuccessfully, to build a canal across the Isthmus of Panama. When it opened, the Suez Canal was only 25 feet deep, 72 feet wide at the bottom, and 200 to 300 feet wide at the surface.
