In the parish there is also a House of Single Mothers, built during the years 1986-1989, parish house from 1993 and the church in Jaroszów from 1999. A ceremonial church fete takes place on 28 October and on Sunday after that day. Żarki was first mentioned in 1382. A deep – rooted legend tells about location of the early settlement on the hill between present Żarki and Jaworznik, nearby existing at that time ruins of St. Stanisław church. Due to the fire, the inhabitants moved to lower parts and that is how new Żarki came into being. In 1406 the town belonged to the king, but then moved to private owners. For a long time it was owned by the Myszkowscy, Korycińscy and Męcińscy families. From the year 1556 Żarki enjoyed the privilege of a market, granted by the king Zygmunt August. The tradition of markets still remains today. In 1831 Żarki properties were purchased by Piotr Steinkeller who transformed the town into a significant industrial district. He built a factory producing agronomic tools, machines used both in coal mining and metallurgy, steam kettles and mail –coaches. A modern sugar factory and brewery came into existence. At that time, Żarki, as the first town in Poland had gas street light.
