Basel, Switzerland - Old Houses

Host Jean recommended to walk to the left of the church on PeterskirchPl to see the homes.  They were charming.  This is the full street view.

 And here are some detailed views of the doors.

 The route turns left at this street-that-is-a-stairway.

And the row of houses are even more charming. This street's name is Petersgasse. (gasse is similar to alley or a secondary street....I gathered).

I turned around and took a photo looking up the street towards the church.

We are in the old town section of Basel.
