Over 400 years old. Only Castle not destroyed or raided left in this area.
Did our own walking tour of Koblenz.
Rainy day in the morning and overcast all day.
A broken lock changed the cruising plans. Usually it's a visit to the Castle only then river cruising. Due to the lock, we also were able to visit Koblenz. Their was an option for a river cruise but you can only see so many castles and villages before they all look alike. The river cruising was done at night but we chose to sleep.
