The Main Square, also known as Rynek Główny in Polish, is the central square of the Old Town of Krakow, Poland. It is one of the largest medieval town squares in Europe and a UNESCO World Heritage Site. The square dates back to the 13th century and has remained the hub of the city's life for over 700 years.

The square is surrounded by elegant townhouses and palaces, including the Cloth Hall, which was originally a trading hall for cloth merchants and now houses shops selling souvenirs and handicrafts. The Town Hall Tower is another notable building on the square and is a remnant of the original Town Hall, which was demolished in the 19th century.

At the center of the square is the Gothic-style St. Mary's Basilica, which features two towers of different heights and the famous hourly trumpet call. The square also has several fountains, including the Adam Mickiewicz Monument, erected in 1898 to commemorate the famous Polish poet.

The Main Square is the site of many events throughout the year, including the Christmas market, Easter market, and the Wianki festival in June. It is also a popular meeting place for locals and tourists alike, and is filled with street performers, musicians, and artists.
