Directly on the banks of the Rhine, the Castle Park at Martinsschloss Lahnstein invites visitors to linger. Surrounded by the historic walls of the medieval castle complex, visitors here enjoy a special combination of nature, culture, and landscape. The freely accessible area offers charming walking paths, shady seating areas, and impressive perspectives. A particular highlight is the location of the William Turner Route: from there, viewers can explore the Rhine landscape from the perspective of the famous painter – with interactive elements and exciting insights into his art.
