Mainz (DE)July 16, 2017 in Germany
Today was the start of the Middle Rhine, the picturesque section with medieval castles. This section has no fewer than 50 castles, and is also know as the Romantic Rhine. All the castles and fortresses are proof that this section of the Rhine was an important trading route during the Middle Ages.
Lining the Rhine from the Netherlands to Switzerland are nine UNESCO World Heritage sites.
