We have got used to seeing the TfL way finder obelisks in central London. It was a pleasant surprise to bump into a couple in the Historic Centre of Mexico City – as my daughter posted out they are the easiest way of finding your way without having to resort to pulling out the phone.
And, yes we were in Mexico City but the central streets are all named after cities and countries eg. Calle Brazil, Calle Haiti, Calle Venezuela, Calle Hamburgo, Calle Londres. A very international outlook.
