i may be going to essen to attend a wedding in late may. provided the virus situation allows travel i am thinking of visiting cologne, trier and worms while i am on the ground. my vague idea is to spend about a week in germany before heading to italy for the bulk of my summer break. my interest is art and architecture, older the better! would love suggestions about other places and sites i am not aware of within a couple of hours train/bus ride from essen. this will be my first trip to the country.
