The synagogue, which is located at a Sderot police station, was officially opened in a ceremony attended by other police officials.
The disaster at Mount Meron took the lives of 45 people and injured over 150 others who had come to the place believed to be the gravesite of the Jewish sage Rabbi Shimon Bar Yochai.
The disaster is one of the largest losses of life in recent Israeli history, and caused May 2 to be marked as a national day of mourning.
