Port 7 – Aachen, the real third Rome

In 2022 I visited the second Rome – Istanbul (was Constatinople, now it's Istanbul, not Constan…). Later in 2022 and in 2023 I visited the first Rome – well, Rome. It was only fair to visit the third Rome, the real one (not that villate in the east), the city of Holy Roman Emperors (Emperors of the Romans), including the first one, Charlemagne – Aachen.
