Training for a fishy business

An average of 25,000 tonnes of fish and fish products are traded each year at Billingsgate Watch: A day at the market Watch: Fish training school

Billingsgate Market has been trading for more than 700 years.

Until 1699 it was a general market, selling everything from corn to coal, but for the past 300 years has only dealt in fish.

The market occupied a site in the heart of the City of London, not far from the Tower.

The original building, now surrounded by the offices of the City's burgeoning financial services sector, was abandoned in 1982.

Billingsgate's current home is a purpose-built complex a couple of miles to the east in London's Docklands.
