The classicist church of St. Alexander on Three Crosses Square is undoubtedly one of the most famous churches in Warsaw. Although it is only 193 years old, its history is as stormy and complex as few of Warsaw's churches. It was built during the Congress Kingdom in the form of a classicist rotunda modeled after the Roman Pantheon. It was thoroughly transformed and expanded in the spirit of the Neo-Renaissance at the end of the nineteenth century, after which it was almost completely destroyed during the Warsaw Uprising, and after the Second World War it was revived in a form similar to the original.→
