The next day we headed to Heidelberg, which is located on the Neckar, a tributary of the Rhine.
For some reason, I liked the city. Maybe because of the shopping street Hauptstrasse, which has plenty of curious establishments. For example, there was a shop selling multicolored tinctures stored in huge flasks - very much like an alchemist's lab; which is exactly the point. Distracted by the sights, I wandered off quite far, and had to run back to catch the bus on time. Luckily, my sense of direction in unfamiliar places, while not perfect, is tolerable, especially when there's a mega-landmark in the form of a long main street and a river flowing parallel to it.
What city this was, I only managed to figure out by the name of the restaurant on the left.
The city had the coolest (according to the guide) half-ruins of a castle bearing the same name as the city, which we went up to on a funicular for a couple of euros. Should have walked it, didn't cross my mind right away.
Little gate.
Looks like a barrel, but actually it's a MEGA-BARREL, one of the largest in the world. It has a diameter of several meters, we went up a little staircase on one side of it and came down the other. Making such barrels is very hard, and this one is not only huge, but also ancient, it's over 150 years old. Not that it's of much use, though - it started leaking very quickly, a few decades after it was made. Repairs prolonged the agony only for a short time.
Looks like a lock.
The castle also had a free museum of apothecary art, but we looked at it on the run, just like many other things during the trip. Unfortunately, the driving always takes a very, very long time. That's why one should spend more time on each attraction. But then you'd either have to see fewer of them, or allocate more time for the whole trip, and that's tough, because then the wondrous gets old.
We went down on foot already, and this cat sat contentedly on a pillar, paying no attention to the crowds of tourists. Funny that the windows are peeling, you don't see that too often.
