Limburg lies in the fertile Limburg Basin between the hills of the Taunus and the Westerwald. It is a town of picturesque half-timbered houses dominated by the Cathedral.
In the center of Limburg's old town, particularly around the Fischmarkt, are numbers of old half-timbered buildings (Town Hall, 14th C.; Hallenhaus, 15th C.). Here too, at No. 22, is the Municipal Art Gallery.
Towering over Limburg's old town, high above the Lahn, stands the seven-towered Cathedral (13th C.; R.C.), one of Germany's finest Late Romanesque churches, with frescoes of the 13th-16th centuries. In the south transept is the monument of Konrad Kurzbold (d. 948), founder of the Cathedral.
