The Świdnicka Cellar (Polish: Piwnica Świdnicka, [pivˈɲit͡sa ɕfidˈɲit͡ska], German: Schweidnitzer Keller) is a Polish restaurant company based in the medieval cellars of the Old Town Hall in Wrocław, Poland.

[1] It is the third-oldest Polish company in existence, as well as the oldest restaurant in Poland and one of the oldest in Europe, having been established in 1273,[1] during Piast-ruled Kingdom of Poland.

[2] The name comes from the nearby city of Świdnica, from which beer was delivered to the restaurant in the Middle Ages.

[2] Świdnica was a renowned brewing centre, and its beer was served in restaurants called "Świdnicka Cellars," which existed in large cities such as Kraków (Piwnica Świdnicka w Krakowie), Toruń, and Wrocław, the last of which still operates to this day.
