Before leaving Trier, we hit Bishop's Museum (Museum am Dom), a small museum with Church and Roman relics that was closed the previous day. They also had a section on Nero, the Roman emperor full of vices. Interesting displays:

Next, we did a longish drive to Baden-Baden, and because it's not a very car friendly city (virtually no parking), we had to park at the casino when we arrived. We arrived there too late to visit the Casino in the morning, and did not feel like dealing with their BS (clothing guidelines, renting a jacket, etc...) to go back later, even if it's supposed to be nice inside. The TI next door was quite nice though, old Roman decors. Of course, I should probably mention now that Baden Baden was an old Roman town too, and it was known for its Roman baths, which have been kept up to date and are still running today (we went that evening after dinner):

Next, we went to a Russian Orthodox Church, which wasn't big, or as nice as the one we had the chance to visit in Nice, France, but still worth a quick visit, especially for all the stuff written in Russian inside :)

what language is this? Arturo?

Since we hadn't parked the car in a final location yet, we used the opportunity to drive to the Funikular that takes you to the summit of Merkur hill. The top had a decent view on the valley and Baden-Baden:

We then drove to the Lichtenthal Abei, but with its limited sporadic opening hours, we got to see nothing, that was a waste:

So we went to our B&B in Baden-Baden to drop off our car in their private garage, and walked around town towards the Lichtentaler alley:

although I had to stop at this bakery on the way :)

sadly that church had just closed by the time we arrived there

Lichtentaler alley is more historical than a must do IMO, but eh, we did a good part of it

the floral garden at the end of our walk, was nice though

We then walked back to town center, had a simple dinner in a cafe:

And then we walked to the Roman baths (Friedrichsbad), and did the full 2H+ 14 course roman bath experience, including a German guy who scrubs you hard with a brush and soap. For some reason, he spent much longer scrubbing naked Jennifer than naked me, I'm not sure why :)
You use the baths naked from start to end, and they are segregated, except for the last 2 big pools, 3 days a week, and mixed the rest of the week. We ended up going on a mixed day, which was fine with us:
