Facts and quotes:
One of the most controversial projects in recent British history, the Millennium Dome encloses 1 million square feet and has the same volume as 1,100 Olympic-size swimming pools. The dome's architects, ever sensitive to the needs of their vulpine visitors, have designed a fox flap for a family with two cubs who have taken up residence in one of the zones.
