Gullaug Church, located in Lier, was first inaugurated as a house of prayer in 1905 and later consecrated as a church in 1925. The church has a rich history, and in 1948 the church bell from Nauen was acquired. The tower was built in 1950, where the bell was moved in, which has contributed to the church's characteristic appearance.
Over the years, Gullaug Church has been the subject of regular maintenance and upgrades, with a new roof being installed in 2017. The church offers various services such as baptisms, confirmations, weddings and funerals. It is part of the Frogner congregation and has a special focus on Sami church life, which reflects the diversity found in the congregation.
