The 1914 Jubilee Exhibition took place in Kristiania, Norway, from May to October 1914. It marked the centennial anniversary of the 1814 constitution and focused on industry and agriculture. The main location was the grounds of Frogner Manor (the site of the current Frogner Park), in addition to a subsection on shipping at Skarpsno at Frognerkilen. The exhibition opened on 5 May, and was closed on 11 October 1914. The total number of visitors was more than 1.5 million. On 11 October, the final day, more than 100,000 visitors visited the exhibition.
The idea for the exhibition is credited to architect Torolf Prytz, in a proposal to the board of Kristiania haandverks- og industriforening in 1907. Prytz became chairman of the planning committee, and later also chairman of the exhibition. Various location alternatives were discussed, including Hovedøya, but it was finally decided on Frogner. In August 1911 the Kristiania city council granted a funding of 300,000 kr to the exhibition, in addition to extra funding for street modifications.
The park area was designed by architect Josef Nickelsen, and leading architects were Henrik Bull, August Nielsen, Rudolf Emanuel Jacobsen and Adolf Jensen. The exhibition showcased developments in Norway over the last 100 years. Among the pavilions were the Industry Hall, the Machinery Hall, restaurants, and more than hundred other buildings. Two locomotives were on display, one constructed at Hamar Jernstøperi og Mekaniske Verksted, the other at Thunes Mekaniske Verksted.Kværner Bruk won a gold medal for their contributions, which included construction elements of the Machinery hall. Lilleborg's soap bubble fountain, which was placed in the Industry Hall, attracted some attention. A department of agriculture included a farm with barn and living house, in addition to separate exhibition buildings for forestry and agriculture. Among the exhibitions was a village with 80 inhabitants brought in from Kongo; it was called the Congo Village.
