[2][4] Construction of Hotel Korpilampi was started in 1975 as a joint venture called Tornilampi by HOK-Elanto, Enso-Gutzeit and the SKOP bank.
The lot designated for construction had a total area of 17 hectares, and construction started by building an artificial pond by moving about 60 thousand cubic metres of mud away from the ground so that the maximum depth of the pond was 12 metres.
As the lot for the hotel was full of rocky ground, it required extensive ground transport work before a basis for a building with 162 hotel rooms, five restaurants and an auditorium with 300 places could be built.
Right from the start, the hotel was marketed in connection with Finnlines as suitable for Middle European passengers of the GTS Finnjet, but this strategy never paid off, but instead HOK-Elanto grew tired of the losses in the early 1980s and sold Hotel Korpilampi to Lomaliitto owned by the trade union association.
The seminar was attended by the elite of the political parties, organisations and businesses in Finland, numbering 350 in total.
