The prayer house at Rødtangen is a memorial from a time when religious activity was central among most people.
In Hurum, the "free church", i.e. congregations outside the Church of Norway, was strong in the 1800s and 1900s. The proportion of inhabitants who were members of other churches was at the top of the country, in the Holmsbu area it applied to almost one in three inhabitants. The free evangelical congregations gathered many, but even the Mormons (The Church of Jesus Christ of Latter-day Saints) came to Holmsbu and baptized people in the Drammensfjord. One of their leaders was fined by the Supreme Court for harmful activities after cutting a hole in the ice to carry out the baptism of five new members in February.
At first, religious meetings often took place in homes, but as the congregations grew, so did the need for separate meeting rooms. The first to be built was the prayer house in Holmsbu, then came the prayer house at Rødtangen in 1909. The local women's association was behind it, and this prayer house had a Lutheran profile, but with freer forms of meeting than the church's services. Sunday school and collections for missionary work were also held here, and much of the activity took place on weekdays, when the churches were closed anyway. It says something about the commitment that the prayer house was built in a place with such a small crowd. Rødtangen was at its highest in 1930 with 148 inhabitants, today there are about 40 permanent residents here.
Today, most of this business has been closed down, and the houses of worship have been sold as private homes or for other purposes. Like the prayer house at Rødtangen, which is now a community house for the entire population, owned by the Rødtangen permanent residents' association. With art exhibitions and cultural activities, this has also become a cultural center that attracts tourists and visitors who do not parish to Rødtangen.The same applies to the village's oldest prayer house, in Holmsbu, which is privately owned and lent out for events and exhibitions under the name "bdhuset".
