Smithfield Market is the largest wholesale meat market in the UK and one of the largest in Europe, located within the City of London. It has been operating as a meat market since medieval times, with a history dating back to the 10th century, making it one of London’s oldest markets.

The market mainly supplies butchers, shops, and restaurants with fresh meat and operates early in the mornings on weekdays
