Muri Abbey
Many of Guntram's possessions had been given to him by the king. In August 952 Guntram the Rich was convicted of treachery during an Imperial Diet in Augsburg, which resulted in King Otto the Great removing these lands from him. Guntram was however able to keep his possessions in Alsace, Breisgau, and near Aare and Reuß. The political influence of Guntram's family was restored by his grandsons. One of them, Radbot, a count in Klettgau, founded the Muri Abbey, which became the first burial place of members of the House of Habsburg. It is possible that Radbot founded the castle Habichtsburg, the residence of the House of Habsburg, but another possible founder is Werner I.
