Lelewel Palace (Polish: Pałac Lelewelów) was a rococo palace on the Miodowa Street in the Warsaw Old Town, which was also unofficially named "Palace Street" (ulica Pałacowa) because of its gorgeous palaces. Lelewel Palace was built in 1755 by Efraim Szreger on an estate documented to have been property of King John III Sobieski and maintaining the original Corps de logis.
