Peter III von Turn
Peter III von Turn headed the leading Valais noble house from the Gestelnburg, with estates in the Bernese Oberland. Succeeding Johann I around 1324, he sold off lands: Laupen to Bern, his Mülenen rights in 1341, and Lauterbrunnen tenants to Interlaken Abbey in 1346.
In 1349 his family feuded with that of Bishop Tavelli of Sion; the war drew in Count Amadeus VI of Savoy, whose troops burned Sion in 1353. Peter died about 1356 and was followed by his son Anton.
