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:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
