The tripto catalogue lists 118 market squares, old towns, plazas and grand streets. They are the easiest trips to plan: walking around is free, and the square is usually surrounded by a town hall, churches and museums.
Kraków's Main Square was laid out in 1257; it holds the Cloth Hall, St Mary's Basilica with its bugle call and the Town Hall Tower, and the Rynek Underground route runs beneath it. Wrocław Market Square covers 3.64 hectares and is one of the largest medieval squares in Europe – with a Gothic town hall and the Piwnica Świdnicka cellar. Zamość Old Town is a Renaissance "ideal city" founded in 1580, with three squares and a place on the UNESCO list, as is Toruń's medieval old town with its Leaning Tower and the ruins of the Teutonic castle. Warsaw's Old Town Market Square was rebuilt after the war from Canaletto's paintings, and in Kazimierz Dolny on the Vistula you will find a square with a well and the Przybyła townhouses.
Most places in this category are in the Silesian region (close to 20), Lesser Poland (close to 20) and Lower Silesia (over a dozen). Warsaw, Kraków and Łódź with Piotrkowska Street lead among cities.
In practice: 20 to 45 minutes is enough for a walk around a square, but with the town hall tower and a museum it becomes half a day. More than a third of the places in this category are marked as free in the catalogue; only towers, underground routes and museums charge. Mornings and evenings are the most pleasant; in December many squares host Christmas markets.
