What's in a Prague street name

Údolní was built in 1925.

At one end of this street, you’ve got a hill with Braník Brewery (no longer brewing) on top of it (https://whatsinapraguestreetname.com/2025/12/13/prague-4-day-258-nad-branickym-pivovarem/).

At the other end, I’m going to assume we’re also on a hill, but will confirm that when we get to the streets around there.

Hills or not, the street is located in a valley, i.e. an ‘údolí’.
