Lovisenberg Church was built for the Deacon House and was inaugurated in 1912. The church was designed by architect Harald Aars and is characterized by a neo-Romanesque style with Gothic features. The building is constructed of red, hand-beaten brick, and the roof is covered with slate. The juxtaposed tower structure gives the church a distinctive profile that sets it apart from other buildings in the area.
Inside, the church room is decorated with stained glass windows made by Maria Vigeland, which contribute to the visual experience of the room. Lovisenberg Church has high mass on Sunday at 11.00 twice a month, which provides an opportunity for congregational life and socializing. The church functions as an important gathering point for the local community.
