As it was appealing due to its rich mines and its good geographical position, Rudnik often changed its masters and was an important political centre for Serbia. Mining led to building multiple settlements for Saxon miners, while the square opening led to the development of trade, and that way people from Dubrovnik, Kotor, present-day Albania (so-called Arbanasi, as they were known at that time), east Serbia, Greece, Venice (though not many), Florence, etc. started living in Rudnik.
In an urban settlement, such as Rudnik of the time, there were three important titles that influenced everyday life: kefalija, the commander of a town and a region, which was usually assigned to a person from Serbia, prince, who was in charge of local inhabitants and who was often from Dubrovnik, and a customs officer who was usually from Dubrovnik or Kotor. A consul from Dubrovnik, who was in charge of the legal protection of citizens from Dubrovnik, also lived in the place.
Following the folk tales that there were some church remains on the Nikić family estate, a team of archaeologists from the Museum of Rudnik and Takovo Region as well as from the Department of Archaeology at the Faculty of Philosophy in Belgrade set a test probe at this site. It confirmed the existence of a rather preserved building, whose inside walls were very picturesque. They continued their exploration in 2011 just to discover a wall with two entrances on the east side of the building where it was expected to find the apse of the church.
A part of the door ornament made of decorative stone named ‘siga’ carved on its both sides was spotted as well. The combination of red, blue and beige triangles filled with floral decoration, was incorporated into the arched door ornament of the following dimensions – 70 x 30 x 25 cm. Judging by the pottery found at the site, the facility could be dating back to the period of XIV – XV century, that is to the heyday of Rudnik. Who was the tenant of this lavishly decorated building? A Serbian squire, a customs officer, a consul or a rich merchant?
