What's in a Prague street name

U Křížku was built in 1930.

A ‘křížek’ is a small cross (a regular-sized cross is a ‘kříž’), and this was once the name of… something round here, probably involving the Holy Cross.

There’s a hill originally named after the Holy Cross, and colloquially also known as Křížek, in Prague 3, and, if you live round there, you’ll know it: https://whatsinapraguestreetname.com/2022/11/26/prague-3-day-91-pod-parukarkou/.
