Its population rivaled in size some of the major cities of the Renaissance world and prospectors were coming from all corners of the continent, some as far as Spain, all of this fueled by the massive amount and quality of ore, so high that on many occasions it was said to be practically pure, metallic silver. Initial growth can be attributed to Jan II the Good, the last Duke of Opole and Racibórz of the first Polish dynasty of Piast, and George, Margrave of Brandenburg-Ansbach (from the House of Hohenzollern), both of whom, in 1526, gave the town special privileges called "Akt Wolności Górniczej" (The Miners’ Freedom Act). This revolutionary document awarded freedom to any peasant who chose to become a miner in the area; the same year new settlement was officially elevated to the town-status, christened Tarnowskie Góry and received additional set of town privileges and rights, cote of arms and official seal followed few decades later in 1562.

Many other associated businesses like trade, manufacturing, crafts etc., were rapidly developing and most of the old-town was already in place by 1540, including many of still existing brick and stone buildings and Protestant church. By the mid-16th century Tarnowskie Góry became the largest mining center in Upper Silesia and one of the largest in Europe; the combined length of main tunnels (main tunnels were the passages with clearance of over in height) constructed under the 1sq mile of old town alone, exceed , still, representing only a small fraction of a total underground system. Many Protestants found refuge in Tarnowskie Góry, and after the death of John II the Good (1532) town was ruled by the family of Hohenzollern, supporters of reformation movement. The first Protestant, wooden church was built in 1529 and two years later a stone structure was erected to replace it.
