When Targ Pod Zamkiem (ENG: Market under the Castle) takes place on Sundays, many curious locals descend upon Plac Zamkowy, the Lublin Old Town's elliptical car park that once constituted a key part of the city's Jewish district, to browse through old antique wares and try grab a bargain. As this description probably hints at, this affair is very much a flea market, although its often referred to as a farmer's market because of its past history as a fresh produce fair in the early 90s. While it promotes itself as an 'every Sunday' event, the event is notoriously infrequent, and often doesn't appear for weeks at a time. What we can say for certain is that it's far more common in the warmer months than the colder ones. Your best option is to keep an eye on the facebook page and try and catch it if and when it happens!
