You have to venture high up into the South American Andes to get to the city we're looking for in today's quiz. It ranks as the highest capital in the world. The festival of flowers and skulls is going on. It follows the Day of the Dead which is also widely celebrated throughout Mexico. But the city we're looking for is a long way south from Mexico.

It's a city steeped in Aymara indigenous tradition -- it's a magical mix of of Catholic beliefs, paganism and superstition. Where else would you skulls with flowers, coca leaves and lit cigarettes poking out their mouths?

We'll walk around the cemetery in this city of skulls and flowers...when we reveal the answer.
