This Icelandic church was chained down in 1900. The site of the church is called Kálfafellsstaður, whose original church was destroyed in 1886 by a storm. The only thing left standing after the destruction was an effigy of Saint Olaf. The church was rebuilt around 1926. So from 1887 to 1925 there should not have been a church – and if there was one, why would it have been chained?
