There is no completely reliable information about the origin of Radul-bey’s residence, the time of construction and the owners. It is still the most beautiful monument of oriental culture in the city, and is located in the centre of Zaječar, in Ljube Nešića Street, which is also a commercial part of the city. It presents us with a picture of what Serbia looked like a couple of centuries ago. It is also known as “Ninuca’s house” or “Chardak”, and it is one of the oldest buildings in Zaječar.
It is not clear who built the residence, but after the liberation of the Timok Valley from the Ottomans in 1833, Radul-bey became the owner of the “konak”, therefore it is known by his name. However, the residence was mentioned for the first time in 1784 in the report of the Austrian officer of Czech origin, Pokorný. According to the legend, konak belonged to an unknown Turkish bey whose name has not been preserved. It was a “road house” for occasional travellers, who were looking for accommodation and food. It had a hammam on the upper floor, and traces of a smithy were found on the lower floor, which indicates that it served the caravan trasvellers for refreshment and repairing horseshoes.
