The North Pole Experience

The North Pole Experience was an interactive museum located on the North Pole, built on the exact same spot in which Martha Jones had become the first person to walk on the North Pole 200 years earlier. The museum had a gift shop that sold clockwork penguins and "I've Been to the North Pole" t-shirts.

Between 2088 and 2092, the Tenth Doctor took Martha to visit. They shared coffee on the museum's observation deck. (PROSE: The Frozen Wastes)
