What is this called?

Other than being very difficult to walk though!  Some folk call it a ginnel or a snicket or a back alley or even a wynd.  Built in the days long before wheelie bins.  Had a very interesting treasure hunt walk round Saltaire with a select few BPW’s, good to have Corinthian restored to walking with us now her foot is much better.  Lunch in the Half Moon Cafe for the second day running!
