The Old Town Market Place, also known as Rynek Starego Miasta, is the historic central square of the Old Town in Warsaw, Poland. It is one of the most recognizable and picturesque landmarks of the city, surrounded by colorful and beautifully reconstructed 16th-century buildings.

The Old Town Market Place was established in the late 13th century, and since then it has been the main market square of Warsaw. It has witnessed many important events in the city's history, including royal coronations, public executions, and uprisings against foreign invaders.

In the middle of the square stands a statue of Warsaw's mermaid, which has become the symbol of the city. There are also several historic landmarks in the area, such as the Gothic St. John's Cathedral, the Warsaw Historical Museum, and the Barbican, which is a fortified gate that used to defend the city in the 16th century.

Today, the Old Town Market Place is a popular destination for tourists and locals alike. It is lined with outdoor cafes and restaurants, and during the summer months, it hosts numerous cultural events and festivals, such as the Warsaw Beer Festival and the Warsaw Jazz Jamboree.
