St. Alexander's Church, Warsaw

St. Alexander's Church is a Roman Catholic church situated on Three Crosses Square in central Warsaw, Poland. It marks the historical southernmost entry into New World Street, the Royal Route and the Old Town. The temple is one of the most recognizable landmarks in Warsaw.

It was designed in the neoclassical style by renowned Polish architect Chrystian Piotr Aigner, and constructed in the years 1818–1825. In the late 19th century, St. Alexander's was remodelled into a larger, more grandiose Neo-Renaissance church, with two side towers and a higher ornate dome. It was destroyed during World War II and reconstructed in its initial simpler form by 1952.
