Trier and cologne trip

Trier is a must visit city that you will never be disappointed by visiting it despite not all people know about it but it really deserve to be there Cologne is a famous city in Germany which is known with it’s famous church it was really nice but i didn’t spend too much time there as it was my last city in my Europe trip and i had a flight next day in the early morning but i liked it and next time i will give it two days in order to make shopping also
