In 2006–2007, a project co-funded by the European Union was carried out in Savonlinna provincial museum in order to develop activities in and cooperation between the local museums in Southern Savo. The funding was received through the Regional Council of South Savo. The aim of the project was to create a development strategy and programme for the local museums in the region, start regional cooperation between museums, encourage the use of local museums by, for instance, the tourism sector, and also make the cultural heritage connected with museums more accessible for the public.

One of the outcomes of the project is the museum website that aims at enhancing the noticeability and familiarity of local museums, strengthening their marketing and also making known the cultural heritage preserved by them.

In addition to the introduction section of the different museums in Southern Savo published on the website in 2007, the site contained web exhibition The Elements of Southern Savo, accompanied with several exhibitions on one of the four elements, water: Vedenkuljetus (Transportation of water) in 2009; Kaivo (The Well) in 2011 and Kaivonkatsoja (The water diviner) in 2013.

In 2020, further web exhibitions were published: Tarinoita syvästä idästä (Stories from the deep East), part 1 (Veera Konsti) and Vanhan kaupungintalon tarina (The story of the old Town Hall) (Toini Kurimo and Kirsti Kukkonen/Nälkälinnanmäki-Seura ry). In 2021, the web exhibition Kylpylaitoksesta terveyskylpyläksi (from St Olav Spa to Savonlinna Health Spa) was published as Savonlinna Provincial Museum’s own production.

Vuodenkierto (Annual cycle), a common yearbook of the museums has been published since 2010.

The Finnish sections of the website have been updated in 2020, when a new section introducing programmatic museum work was published. The English sections have been updated in 2021.
