magnates often undertook construction projects as monuments to themselves: churches, cathedrals, monasteries ("pic. 14"), and palaces like the present-day presidential palace in warsaw and pidhirtsi castle built by grand hetman stanisław koniecpolski "herbu" pobóg. the largest projects involved entire towns, although in time many of them would lapse into obscurity or be totally abandoned. usually they were named after the sponsoring magnate. among the most famous is the town of zamość, founded by jan zamoyski and designed by the italian architect bernardo morando. the magnates throughout poland competed with the kings. the monumental castle krzyżtopór, built in the style "palazzo in fortezza" between 1627 and 1644, had several courtyards surrounded by fortifications. due to efforts of powerful radziwiłł family, the town of nesvizh in today's belarus came to exercise significant influence in many domains – the nesvizh manufactures of firearm, carpets, kontusz sashes and tapestries as well as school of painting produced renowned and luxury items.
