The Main Square (Polish: Rynek Główny [ˈrɨnɛɡ ˈɡwuvnɨ]) of the Old Town of Kraków, Lesser Poland, is the principal urban space located at the center of the city.

The center of the square is dominated by the Cloth Hall (Sukiennice), rebuilt in 1555 in the Renaissance style, topped by a attic or Polish parapet decorated with carved masks.

Kraków was the capital of the Kingdom of Poland and a member of the Hanseatic League and the city flourished as an important European metropolis.

In addition to its original merchant functions the Main Square witnessed many historical events, and it was used to stage public executions of prisoners held in the city's Town Hall.

It was a place of regal ceremonies as part of the Royal Road (Droga Królewska), frequented by diplomats and dignitaries traveling to Wawel Castle.

Jan III Sobieski, a King of Poland and Grand Duke of Lithuania, celebrated there his victory over the Turkish Empire in the 1683 Battle of Vienna.

In 2013 Lonely Planet travel guides rated Kraków's Main Market Square as the most beautiful in the world.

One of the most renowned, Pod Palmą (Under the Palm) at Krzysztofory Palace, was opened in 1876 by Antoni Hawełka, a purveyor to the imperial court in Vienna.

Probably the most famous of the oldest establishments is the Wierzynek's restaurant, remembered for the great feast of 1364 which, according to the legend, lasted for twenty one days and helped to reach a consensus between the monarchs of Europe.

The ground floor is continually used for commerce with its many souvenir shops and cafés; upstairs houses the Gallery of the National Museum.

Many cellars are now transformed into pubs and restaurants; other include the Theater Maszkaron and a small archeological museum in the basement of the St. Adalbert's church.

Near Sienna Street there is another underground hall (Kramy Bogate), with 1,200 square metres (13,000 sq ft) of trading area.

The culture of Kraków is deeply rooted in colorful traditions with the Main Square remaining most lively and crowded year-round.
