Havelské tržiště

This is a fairly modest little market located close to Prague’s old town square (roughly a 3 – 5 min walk just a couple of blocks away). I actually just happened to stumble upon this place after wandering around the area.
The market is full of trinkets and items that’s very tourist-​centric. Many of the proprietors sell cheap shit like magnets, cups, post cards etc. Some of the shops carry produce or simple fruits and vegetables. A few others feature local artisans who sell handmade jewelry and paintings. Even though generally this place feels touristy, some of the stuff did feel very local and cool. I ended up buying a few small paintings because of the nice drawings of St. Charles bridge and other local attractions.
Personally I think this isn’t a place that you make a point of visiting unless you had some extra free time and wanted to check out some reasonably priced items to take back home with you (if you’re a tourist). However, if you do stop by, I wouldn’t be surprised if you do happen upon this place that you’ll still take a few minutes to check out what they have. Some merchants here are more pushy than others but generally they are all ok. Some of them are also flexible about bargaining.

The Havelské Tržiště (literally in English Havel’s Market) is a permanent outdoor market close to the Old Town Square (Staroměstské Náměstí) and the Můstek
metro stop. Beyond just being darned cute, I’ve found it to have some of the best prices and selection for touristy items near the Old Town – postcards (only Kč 5), magnets, mugs, and kitschy items abound, but you’ll also find nicer options than in the made-​in-​China neon souvenir shops. My favorites are local artwork (both originals and prints), tea and food items, and metal and ceramic jewelry. I’ve brought home most of my gifts from here both times I’ve come to Prague.
Unlike in most of Prague, the prices posted are somewhat negotiable – but not terribly, usually sticking close to what is posted. However, you’ll find a significant price variation from stall to stall, so it behooves you to look around before you make your final purchases. The painting we got (the exact print) ranged from Kč 450 to Kč 700 depending on the stall, and fruit and snacks had a variation of about Kč 10.

The Havelska Market caters mostly to tourists. It’s a good place to pick up some cheap souvenirs. The market is small enough that you can do a quick walk around all of the stalls to see what’s there first. Then you can go back to the places that piqued your interest. I generally stuck with the fresh fruit whenever I stopped by. You can get individual pieces of fruit that are great snacks to tide you over until mealtime. I did pick up a few magnets and post cards to send back to people at home. It’s fairly cheap and you can barter with the vendors if you are inclined to do so. You won’t find anything outstanding here, but it is local flavor.

This market is definitely not the most impressive in central Europe, but it was alright. They have a lot of small gift items that are at least somewhat less touristy than all of the surrounding shops (but still obviously aimed at tourists). The fruit and veg selection is minimal. The stop is still worthwhile, but don’t expect anything amazing.

Rick Steve’s def mentioned this super duper historic area of farmers marketing, long before it was even in style in America.
Close to the corner of Melantrichova and Havelska streets… get the schedule of when they’re out selling.
Make like a local while being a tourist.
