The Camden markets are a number of adjoining large retail markets in Camden Town near the Hampstead Road Lock of the Regent's Canal (popularly referred to as Camden Lock), often collectively named "Camden Market" or "Camden Lock". Among products sold on the stalls are crafts, clothing, bric-a-brac, and fast food. It is the fourth-most popular visitor attraction in London, attracting approximately 100,000 people each weekend.[1] A small local food market that has operated in Inverness Street since the beginning of the 20th century has lost stalls since local supermarkets opened, and as of 2012 this market retains only two fruit and vegetable stalls (which are closed on Sundays), in addition to stalls similar to those of the other markets. Since 1974 a small weekly crafts market that has operated every Sunday near Camden Lock has developed into a large complex of markets.[2] The markets, originally temporary stalls only, extended to a mixture of stalls and fixed premises. The markets originally operated on Sundays only, which continues to be the main trading day. Opening later extended to Saturdays for most of the market. A number of traders, mainly those in fixed premises, operate throughout the week, although the weekend remains the peak period.
