1500 – 1546 The copper that travelled the worldMeď, ktorá precestovala svet

At its height the company was one of the leading copper producers in the world. Ore came down from Špania Dolina and the valleys around it, was smelted in works along the Hron, and travelled north to Kraków and Gdańsk and west to Antwerp — and from there into cannon, kettles, roofs and coins across Europe and beyond it. About a thousand people worked for the firm, and it kept an infirmary for them, which was early and unusual and tells you exactly how valuable a trained miner was. The palaces along SNP Square are that business written in stone. The Thurzo House, the company's own building, is today the Central Slovakia Museum.Vo svojom vrchole patrila spoločnosť k popredným producentom medi na svete. Ruda schádzala zo Španej Doliny a okolitých dolín, tavila sa v hutách popri Hrone a putovala na sever do Krakova a Gdanska a na západ do Antverp — a odtiaľ do diel, kotlov, striech a mincí po celej Európe i za jej hranicami. Pre firmu pracovalo asi tisíc ľudí a mala pre nich vlastnú ošetrovňu; na tú dobu to bolo nezvyčajné a najlepšie to ukazuje, akú cenu mal vyučený baník. Paláce na Námestí SNP sú tento obchod zapísaný v kameni. Thurzov dom, vlastná budova podniku, je dnes Stredoslovenským múzeom.
