The Christmas market on Peace Square (Náměstí Míru) opened on Monday. I dropped by a couple of days ago and was surprised to see how busy it was. Shoppers were finding lots of dárky and doplňky, along with the usual market staples of medovina, svařené víno, and trdelník.
Tomorrow, the Christmas market opens at Republic Square (Náměstí Republiky). The biggest markets, which are on Old Town Square and Wenceslas Square, open next weekend. We have details on our Prague Christmas Markets page.
