St. Anne's Church is a church in the historic center of Warsaw, Poland, adjacent to the Castle Square. It is one of Poland's most notable churches with a Neoclassical facade. The church ranks among Warsaw's oldest buildings. Over time, it has seen many reconstructions, resulting in its present-day appearance, unchanged since 1788. The present façade was built in 1788 in a Neoclassical style typical of the reign of King Stanisław August Poniatowski, by Chrystian Piotr Aigner. Sculptors of that time were Jakub Monaldi and Franciszek Pinck, who carved statues of the Four Evangelists which decorate the façade. The interior of the church is now in high-baroque style with several chapels. The church makes an overwhelming impression on the visitor with its surprisingly rich interior filled with frescoes.
