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.
Waldemar Hansteen
He is most associated with his work on Tostrup Yard ("Tostrupgården"), a business premises on Karl Johans Gate in Oslo. The structure was designed by architects Christian Fürst, Torolf Prytz, and Waldemar Hansteen and built between 1896-1898. The five story building was one of the oldest in Norway with load-bearing structures in steel. It was also among the first to have an elevator and use electric lighting.
