an important role in the management of the lahngau was taken by the monasteries and original parishes. at the beginning of conradine rule in the lahngau, the only existing monastery was that of st. lubentius in dietkirchen, which was probably founded as early as the 6th century. the first mention of this monastery was only in 841 as a “"monasterium"” (hermitage). in 845 count gebhard founded the st. severus abbey in the kettenbach, which would later in his lifetime relocate to gemünden. at the beginning of the 10th century, other conradine foundations followed: st. george in limburg (910), st. walpurgis abbey in weilburg (912), and st. mary's abbey in wetzlar (914/15).
