The mining town of Røros is sometimes called Bergstaden which means "the mining town" due to its historical notoriety for copper mining. It is one of two towns in Norway that were historically designated "mining towns", along with the "silver-town" of Kongsberg. The modern-day inhabitants of Røros still work and live in the characteristic 17th and 18th century buildings which have led to its designation as a UNESCO World Heritage Site in 1980. Røros has about 80 wooden houses, most of them standing around courtyards. Many retain their dark pitch-log facades, giving the town a medieval appearance.
Røros Church (Norwegian: Røros kirke, also known as Bergstadens Ziir) is a parish church in the municipality of Røros in Sør-Trøndelag county, Norway. The church is located in the mining town of Røros. Røros Church is Norway’s fifth largest church, and has about 1600 seats. It is also ranked by Riksantikvaren as one of the ten most important churches in Norway.
The church was consecrated on 15 August 1784 by Bishop Marcus Fredrik Bang. Røros Copper Works paid for the building of the stone church, and the symbol of the Copper Works was put on all sides of the tower wall. There is a sign over the entrance to the church that says "Til Guds Ære og Bergstadens Ziir" which means "to God’s Glory and Bergstaden’s beauty." Bergstaden means "the mining town", and this is why the church is sometimes referred to as "Bergstadens Ziir"
About the organ: It is the oldest organ in Norway which can still be played. it was built between 1680 and 1690 for the old church. In 1784 is was placedin the present church, and at that time the front was made in Louis-XVI-style. The frontpipes are made of wood. In 1995 the restauration of the organ was done by the Danish organbuilder Fabricius Husted.
