Trinity Church (Trefoldighetskirken) is the third church in Arendal, and all had the same name. Plans to build the present church was adopted by the Arendal town council in 1883.
The first church was built in timber in direction east-west. The eastern section was divided into two wings, one was the altar and the king's chair, the other an organ. The pulpit was placed where the wings meet. The church was consecrated on 6 December 1670 and was named 'Holy Trinity'. The church became too small and was demolished in 1832 to make room for the new church.
The town's second church was built in the Empire style in 1836 in the same location as the first church. This church was designed by Christian H. Grosch, was octagonal, and had 555 seats. The foundation stone was laid down in 1833 by Crown Prince Oscar (later King of Sweden and Norway). The church had no altar, but a large gypsum replica of Bertel Thorvaldsen's famous Christ sculpture.
In 1880, when Arendal was at the height as a town based on shipping, it was decided to build a new church. It was then announced an architectural competition to design the church. The competition was won by the 27-year-old architect Christian Fürst who was a student of the German architect Johannes Otzen. The foundation stone was laid down on 7 August 1885, and was performed as a large ceremony. This Trinity Church is built of brick. The church has 1.200 seats and is the largest in Aust-Agder County.
The roof is covered with copper plates. The influence of Otzen is also seen in the use of materials, a brick stone type with smooth surface. The altarpiece scene is 'Jesus blesses the eleven apostles before his ascension'. The altarpiece is painted by August Eiebakke.The church has three church bells in addition to a carillon.
Trinity Church is located in a sloping terrain in Arendal, and to make the church worthy surroundings, it was just after the church was built built a church bazaar around the church into the street. Church Bazaar have round arches, and is the only church bazaar in Norway which are designed and built simultaneously with the church.
References:Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
