One way to wander up and down Wenceslas Square, practically without stepping outside, is via Prague’s very cool (and warm in the winter) passageways. Called "pasáž" they are a fun way to skip the crowded sidewalks of the square and typically find some interesting architectural features. With the first built at the start of the 20th century, the passageways are mainly found in the Prague New Town neighbourhood of Prague 1.
