Axel Nicolai Herlofson was imprisoned in which medieval castle near Oslo, Norway?
Axel Nicolai Herlofson Axel Nicolai Herlofson (29 August 1845 in Østre Moland – 1910 in Christiania) was a Norwegian fraudster who is known for causing the Arendal crash, after defrauding customers and co-owners of Arendals Privatbank which he had co-founded in 1874. His scheme had some similarities to a Ponzi scheme, and he had systemically falsified the bank's accounts for several years to cover up being insolvent. In 1886 the bank went bankrupt, and an investigation of Herlofson was initiated. He attempted to flee the country, but was arrested in the last minute and sentenced to six years imprisonment with hard labour, which he served in Norway's strictest prison at Akershus Fortress. He died in Christiania.
Oslo Oslo ( , , ] ] ] ) is the capital and the most populous city in Norway. It constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by Harald Hardrada, the city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 and with Sweden from 1814 to 1905 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, the city was moved closer to Akershus Fortress and renamed Christiania in the king's honour. It was established as a municipality ("formannskapsdistrikt") on 1 January 1838. Following a spelling reform, it was known as Kristiania from 1877 until 1925, in which year its original Norwegian name of Oslo was restored.
