Piotrków Trybunalski ([ˈpʲɔtrkuf trɨbuˈnalskʲi] ; also known by alternative names), often simplified to Piotrków, is a city in central Poland with 71,252 inhabitants (2021). It is the capital of Piotrków County and the second-largest city in the Łódź Voivodeship.
Founded in the late Middle Ages, Piotrków was once a royal city and holds an important place in Polish history; the first parliament sitting was held here in the 15th century. It then became the seat of a Crown Tribunal, the highest court of the Polish–Lithuanian Commonwealth. The city also hosted one of Poland's oldest Jewish communities, which was entirely destroyed by the Holocaust. The old town in Piotrków features many historical and architectural monuments, including tenements, churches, synagogues and the medieval Royal Castle.
