Žalec was attested in written sources as Saxenburc and Sachsenwelde in 1182 (and as Saschenvelde in 1232 and Sachsenfelde in 1256). The medieval German names are based on folk etymology from the Slovene name, probably the genitive of the plural form *Žalci. This in turn was based on the personal name *Zal and would mean 'descendants of Žal'.[4] In modern German the settlement was known as Sachsenfeld.[2][5]
Church
The parish church in the settlement is dedicated to Saint Nicholas and belongs to the Roman Catholic Diocese of Celje. It was built between 1903 and 1906 on the site of a 16th-century church. The 16th-century building had a walled enclosure to protect the locals against Ottoman raids. A round tower from this enclosure still stands next to the church.[6]
