[Q]: Passage: Medieval Kraków was surrounded by a 1.9 mile (3 km) defensive wall complete with 46 towers and seven main entrances leading through them. The fortifications around the Old Town were erected over the course of two centuries. The current architectural plan of Stare Miasto—the 13th-century merchants' town—was drawn up following the Tatar invasions of 1259 and 1287. It features the centrally located Rynek Główny, or Main Square, the largest medieval town square of any European city. There is a number of historic landmarks in its vicinity, such as St. Mary's Basilica (Kościół Mariacki), Church of St. Wojciech (St. Adalbert's), Church of St. Barbara, as well as other national treasures. At the center of the plaza, surrounded by kamienice (row houses) and noble residences, stands the Renaissance cloth hall Sukiennice (currently housing gift shops, restaurants and merchant stalls) with the National Gallery of Art upstairs. It is flanked by the Town Hall Tower (Wieża ratuszowa).
