The municipality of Großsolt is located about ten kilometers south of Flensburg and consists of the villages Großsoltholz ( Store Soltskov ), Großsoltwesterholz, Großsoltbrück ( Store Soltbro ), Bistoft, Estrup, Kollerup, Mühlenbrück ( Møllebro ) and Großsolt itself.
The Bondenau and the Kielstau, from which further west the Treene emerges, flow through the municipality from east to west and end in the Treßsee .
The landscape is hilly and consists mainly of Weichselian ground moraines and inland sand . Großsolt is one of the landscape fishing .
Großsolt was first mentioned in 1352. The name originated from the original name of today's eastern Treßseeniederung . The shore of the lake was located near the village until the early modern period  . The ending "-solt" comes from "sulz" for marsh, marshy terrain. A derivation in the meaning of "salt", as it occurs in some Schleswig field names, however, seems unlikely  .
Until the 20th century, people were fishing in Großsolt. By the river regulation of the Kielstau and the Bondenau 1925 and the land consolidation in the 1960er and 1970er years silted up originally probably more than one hundred hectares large Treßsee ever further. The salmon died and the fishing rights, once a guarantee for prosperity, became meaningless.
At the end of the Second World War, in May 1945, Heinrich Himmler temporarily stayed with his entourage in Kollerup ( ♁ Lage ). Himmler had come to the Flensburg area via the so-called Rattenlinie Nord to take part in the last Reich government in Flensburg - Mürwik . Since it was not received in the Flensburg government in the special area Mürwik, he then fled further south into the Lower Saxony area, where he was captured by British soldiers and shortly afterwards on May 23, 1945 in Lüneburg bySuicide died.
