Day 1 — Old Town: Republic Square and Plzeň’s “tall needle”
🚶 Start at náměstí Republiky — the city’s proper, almost Renaissance square. In the center stands St. Bartholomew’s Cathedral with a 102+ meter spire: the narrow stairs up the tower are rewarded with views of red rooftops and the Radbuza River. Walk around the Renaissance Town Hall, the three modern fountains — “Angel,” “Potter,” and “Sickle” — and slip into quiet alleys with historic portals. By evening, take an unhurried loop along the embankment to the “Plzeň Venetians” of Mlýnská strouha: water, granite, tree shadows, and the first sips of local pilsner.
