The Presidential Palace in Warsaw, formerly known as the Koniecpolski, Radziwiłł, and Namiestnikowski Palace, is a monumental building located on Krakowskie Przedmieście Street. It is the largest palace in Warsaw, and its current neoclassical style was achieved during a reconstruction between 1818 and 1819 under the direction of Christian Piotr Aigner. The building consists of a four-story main body and two side wings, with its façade adorned with Corinthian half-columns and pilasters. The palace has a rich history, beginning with its construction in the 17th century as a residence for Hetman Stanisław Koniecpolski. After various owners, including the Radziwiłł family, it served as the seat of the governors of the Kingdom of Poland, the Council of Ministers, and currently the President of the Republic of Poland. The palace has been the site of significant historical events, including Frédéric Chopin's first public concert in 1818 and the Round Table Talks in 1989. Ceremonies such as the presentation of judicial appointments and meetings with foreign heads of state are held in its halls. The palace garden, covering an area of approximately 1.9 hectares, retains terraces with Baroque elements and a fountain from the 1930s. The building features numerous commemorative plaques, including those honoring Lech Kaczyński and Chopin's first concert. The palace is listed in the register of historical monuments, highlighting its architectural and cultural significance.
