The Great Synagogue – Sydney

The Great Synagogue, 166 Castlereagh Street Sydney, NSW 2000

Cardo Property is proud to announce our appointment as The Development Management Company overseeing the upgrade works at The Great Synagogue of Sydney, NSW.

The Great Synagogue

Since 1878, The Great Synagogue has been home to a thriving congregation and remains a vibrant hub for prayer, learning, support, and celebration. As one of Australia’s most recognisable and visited Jewish landmarks, it has been a majestic feature of Sydney’s cityscape for over 140 years, facing Hyde Park with its striking architectural beauty. We are honoured to be entrusted with this significant project and extend our gratitude to the Board of Directors, Rabbi Dr. Benjamin Elton, David Lewis and Rabbi Menachem Feldman for the opportunity to contribute to this historic institution. Special thanks to Adam Pisk and George Bensen for their collaboration in bringing this vision to life.

As members of TGS, my family and I take great pride in being part of this exciting venture.
