'Guardian of Patriarchs' or 'Shield of our Fathers') is an Hasidic Jewish congregation and synagogue, located at 24/26 Waterloo Street in Rochor, within the Central Area of Singapore.

As early as 1831, Singapore's earliest Jewish settlers were Mizrahi/Sephardic merchants from mainly modern-day Iraq and Iran who came to trade.

The synagogue started to hold a congregation of approximately 40 and served the local Jewish community for 30 years before it was sold.

[1][6] During the Japanese Occupation of Singapore, the synagogue was a significant gathering place for the local Jews to exchange news and collect funds to help those in need.

[3] In the past, oil lamps were used during services and they still remain in the present day, hanging from steel rods in loving memory of those who have passed on.

He also reportedly planned to travel to Gaza to join Hamas' military wing, the Izz ad-Din al-Qassam Brigades.

Therefore, the original simple design was deemed inadequate and thus, later constructed to be a solid gallery which was added to the main building which remains in use today.

[17] Despite the deliberate simple design of the synagogue, the building still remains to be elegant due to the combination of its timber-louvred windows, marble floors and red carpets with teak and rattan pews.
