What's in a Prague street name

V Ondřejově was named in 1935.

Emergency colony time again; same one that was discussed, briefly, on https://whatsinapraguestreetname.com/2025/09/08/prague-4-day-166-nad-ondrejovem/.

In order to make sure today’s post isn’t completely devoid of new information: Ondřejov is also the name of a former village which is now part of Prague-East.

It’s mainly known for the Ondřejov Observatory, principal observatory of the Astronomical Institute of the Czech Academy of Sciences, and home of the country’s largest telescope: https://www.asu.cas.cz/cz/verejnost-a-media/prohlidky-pro-verejnost.
