The fountain below is the the patio of the Allende Institute, which I think is a language and art school for foreigners, but I very easily could have that wrong. The Institute is in a beautiful building that looks very old.
This windowbox was the second story window of a one door/one window two story house about 15 feet wide.
I keep walking along, hoping I was heading in the right direction. I was, because a Colonia Antonio bus came along and picked me up. My comforting back-up plan for if I get lost is to take a cab home. For 20 pesos. Can't lose, and it makes me feel brave to know I can just wander around anywhere, because a taxi will always show up and take me home.
