My fatehr and I traveled to Verkhni Petrivsti (פטראוץ) Ukraine in June, 2019. We were led by local villagers to a monument on the site where the synagogue stood. The monument is behind a cement wall in the back yard of a private residence. It cannot been seen from the road and its existence is not known to all the villagers.
The estimated coordinates of the monument are 48.046885,25.744063 .
