The Isaac Agree Downtown Synagogue (of Detroit) explains that:
The Isaac Agree Downtown Synagogue (IADS) was established in 1921, at a time when there were many synagogues located in Detroit. Its principal mission was to address the unmet needs of the Jewish community ― particularly for those who worked downtown, were unaffiliated with another synagogue, or were visiting the city―by providing a traditional (Conservative) Jewish presence in the heart of Detroit.
…As much of the Jewish community migrated to suburban Detroit, the IADS―like the city itself―has suffered from a shrinking population and a depletion of resources. In recent years, daily services have, of necessity, been eliminated. However, the Downtown Synagogue proudly continues to offer weekly Sabbath services, as well as High-Holiday services, the latter of which attracts hundreds of worshippers.
The Synagogue is currently housed in a historic four-story building, a building that it has occupied and owned since the early 1960s. Located at 1457 Griswold Street, it is well situated, but is in serious need of major repair. Currently, parts of it are unusable. However, the unique triangular design creates an uncomparable, interesting space. The potential for this building is far from being realized.
This Sunday (August 19), they are offering J-Cycle, a bicycle tour of historic Jewish Detroit. A portion of the proceeds will be donated to the Back Alley Bike Project, at the Hub of Detroit, a non-profit organization providing cycling education and services with a focus on youth development, sustainable practices and community access.
