On the outskirts of Koblenz, the neo-Gothic towers of Schloss Stolzenfels come into view. The castle's origins date to the mid-13th century, when the archbishop of Trier sought to counter the influence (and toll rights) of the archbishop of Mainz, who had just built Burg Lahneck, a castle at the confluence of the Lahn and Rhine rivers. Its superbly furnished period rooms and beautiful gardens are well worth a visit. From B-9 (curbside parking) it's about a 15-minute walk
to the castle entrance.
