St. Pancras functions as the gateway to Northern Europe and is one of the busiest train stations around.
Whilst St. Pancras was originally a medieval parish covering a fairly large area, these days it refers just to the great train station that serves so many travellers each year.
The station has undergone an £800million refurbishment, meaning there is a fair bit to see and do whilst you wait for your train.
It is mostly associated with the Eurostar services to Paris and Brussels, indeed for many people a wait at St. Pancras signals the beginning of an exciting holiday.
In 1967, a campaign led by the poet Sir John Betjeman saved St. Pancras from a planned demolition, and managed to reverse the decision to such an extent that the building was certified as protected and awarded a Grade I listing.
