Beth Sholom: Frank Lloyd Wright's Only Synagogue

A Mountain Made of Light

In the Philadelphia suburb of Elkins Park, Pennsylvania, a translucent pyramid rises from the landscape like a jewel set in a suburban lawn. Beth Sholom Congregation — completed in 1959 — is the only synagogue ever designed by Frank Lloyd Wright, America’s most celebrated architect. Wright called it “a mountain of light, a luminous Mount Sinai.”

It was among the last buildings Wright designed. He died on April 9, 1959, just months before the synagogue’s September dedication. He never saw it completed, but he considered it one of his most important works.

The Meeting of Rabbi and Architect

The building exists because of a remarkable partnership between Rabbi Mortimer J. Cohen, the spiritual leader of Beth Sholom, and Wright. In 1953, Rabbi Cohen wrote to Wright, asking if the architect would consider designing a synagogue. Cohen had long admired Wright’s work and believed that Wright’s organic architectural philosophy — buildings that grow naturally from their purpose and environment — was ideally suited to Jewish worship.

Wright, then eighty-six years old, responded with enthusiasm. He had designed hundreds of buildings — homes, museums, offices, churches, hotels — but never a synagogue. The two men began a correspondence and collaboration that continued until Wright’s death.

Wright immersed himself in Jewish theology and symbolism. He studied the descriptions of the Tabernacle in Exodus, the concept of a portable sanctuary that the Israelites carried through the wilderness. He wanted Beth Sholom to capture the feeling of that ancient tent — a structure of light and shelter, a place where the sacred could dwell.

Design and Structure

The building’s form is a massive tripod — three concrete piers supporting a pyramidal superstructure of steel, aluminum, fiberglass, and wire glass. The walls are translucent, not transparent: during the day, sunlight filters through them in a diffused, ethereal glow. At night, interior lighting makes the entire building radiate outward, visible for blocks in every direction.

The pyramid shape represents Mount Sinai, the mountain where Moses received the Torah. Wright imagined the congregation gathering inside the mountain, as if receiving revelation themselves. The roof’s ridgeline suggests the Ten Commandments tablets, and the overall form evokes both a tent and a mountain — the Tabernacle and Sinai fused into a single architectural gesture.

The sanctuary seats approximately 1,020 worshippers. The interior is a single vast space, with no columns to obstruct the view. The Aron Kodesh and bimah are positioned at the front, and the seating rises in tiered rows, giving every worshipper a clear sightline.

Wright’s Jewish Vision

Wright’s letters and notes reveal how seriously he engaged with the project’s spiritual dimensions. He wrote to Rabbi Cohen: “The synagogue should be a place where the light of God can be felt as truly present.” He designed the building so that light itself — natural, shifting, alive — would be the primary decorative element.

This approach aligned with a deep Jewish sensibility: that the divine presence cannot be captured in images or statues but can be suggested through intangible qualities like light, sound, and space.

National Historic Landmark

Beth Sholom was designated a National Historic Landmark in 2007, recognized as the only synagogue by America’s greatest architect and as a masterwork of mid-century modern design. The building has been featured in architectural surveys, exhibitions, and publications worldwide.

A Living Congregation

Beth Sholom remains an active Conservative Jewish congregation. Shabbat services are held weekly in Wright’s luminous sanctuary, and the building hosts lifecycle events, educational programs, and community gatherings. The congregation has carefully maintained the building while adapting it for contemporary use.

For visitors — whether drawn by architecture, Jewish history, or both — Beth Sholom offers a singular experience: standing inside a mountain of light, in a space designed by a genius and a rabbi who believed that architecture could bring people closer to the divine.
