Most German cities have an Altstadt and it is always a prime destination for tourists. Same in Frankfurt Am Main ; it is a most picturesque place, especially when the Christmas tree and decorations ..

Nice town square in the old town of Frankfurt. Very quiet on New Year's Day but assume it'd be busy and lively on other non holiday days! The buildings are lovely and there are some really quaint pubs

Located in the heart of old town Frankfurt is this area and main square with stunning building and an old feel atmosphere. There is a lot to see and take photos of, especially over the festive period
