Editing Lahn (section)

===Lower Lahntal===
Below [[Diez, Germany|Diez]], the Lahn absorbs the [[Aar (Lahn)|Aar]] from the south. At Fachingen in the municipality of [[Birlenbach]], it leaves the Limburger Basin and enters the Lower Lahntal.  Its course is incised over {{convert|200|m|ft}} deep in the Slate Mountains. Near [[Obernhof]], the [[Gelbach]] enters the Lahn opposite [[Arnstein Abbey]]. Then, after passing [[Nassau, Germany|Nassau]] and [[Bad Ems]], where, as in Fachingen, mineral springs (sources of Emser salt) can be found, it completes its {{convert|242|km|mi|abbr=on}} run, entering the Rhine in [[Lahnstein]], located five kilometers south of [[Koblenz]] at an elevation of {{convert|61|m|ft}}.
