The Old Town, along with the adjacent New Town, is one of the most beautiful and most often visited sites in Warsaw. The buildings were originally built in the 17th and 18th centuries. Burned down during World War II, the Old Town was meticulously reconstructed after the war. Its numerous colorful tenements with red sloping roofs and characteristic street lamps combine to create a picturesque panorama. Syrenka ("a little mermaid") is a symbol of Warsaw.
