It’s both a wholesale and retail market and has in recent times become synonymous with speciality foods, both from the UK and continental Europe.
Southwark was the first of London’s 32 Boroughs, and in the early days was just known as The Borough, so it’s not difficult to see how the Borough Market got its name.
Apparently, there’s been a market at the southern end of London Bridge in various forms since 1014, which meant that there didn’t need to be any arm-twisting to celebrate its 1000th birthday in 2014. How the powers that be would have known it started up in 1014 precisely I’m not quite sure, but I’ll take their word for it.
It’s not difficult to see why a market was set up here in the first place though because it would have been an ideal location to sell goods to travellers making their way in and out of London over the bridge to and from the south.
