The Temple of the Sibyl (in Polish, Świątynia Sybilli) is a colonnaded round monopteral temple-like structure at Puławy, Poland, built at the turn of the 19th century as a museum by Izabela Czartoryska.
The so-called Temple of the Sibyl at Puławy, also known as the "Temple of Memory," opened in 1801. The structure was modeled after the similar monopteral "Temple of Vesta" at Tivoli, Italy, the site of the Tiburtine Sibyl, which was well known throughout Europe in engravings. The Puławy temple, designed by Polish architect Chrystian Piotr Aigner, memorialized Polish history and culture, and the glories and miseries of human life. Items kept in the Temple of the Sibyl included the Grunwald Swords and a large "Royal Casket" containing portraits and personal items of Poland's monarchs and queens.
During the November Uprising of 1830–31, the museum was closed. Izabela Czartoryska's son Adam Jerzy Czartoryski evacuated surviving collections to Paris, France, where he housed them at the Hôtel Lambert. His son Władysław Czartoryski later reopened the museum in 1878 in Kraków, in Austrian Poland, as the Czartoryski Museum.
