St. Hanshaugen
To the southeast of the park is Oslo’s oldest building – Aker Kirke, built around 1100, but restored from ruins around 1860, and then again in the 1950s in a more authentic style. Next to the church is the cemetery Vår Frelsers gravlund, created in 1808 as a result of the great famine and cholera epidemic of the Napoleonic Wars. The nearby area around Damstredet and Telthusbakken is interesting since it retains the small town character of Oslo in the first part of the 19th century.
Trinity Church (Oslo)
Trinity Church (in Norwegian, Trefoldighetskirken), is a church in the Hammersborg neighborhood in central Oslo, Norway. Trinity Church is neighbor of the government buildings in Regjeringskvartalet. It is the parish church of the parish of Trinity, belonging to the Diocese of Oslo of the Church of Norway. It is one of the largest churches in Oslo (1000 seats). The church itself is in the raw red brick, while the vaults, arches and small columns have gray scale color. The nave is octagonal with a Greek cross superimposed, with the choir in the apse, shallow transept and rectangular entrance flanked by two slender, octagonal bell towers. A central dome rises above the church. Trinity Church is the largest church in Oslo and one of the largest of the many octagonal churches in Norway, but one of few octagonal churches constructed in red brick.
