Introduction: The Synagogue—More Than Just a Building

As a synagogue interior design firm, we’re intimately familiar with what defines a synagogue.

A synagogue, known in Hebrew as a beit knesset (house of gathering), is far more than merely a physical structure. It serves as the spiritual, educational, and communal heart of Jewish life. As Rabbi Jonathan Sacks, the renowned British philosopher and theologian, eloquently explained:

“The synagogue is the home we build for God, but it is also the home we build for one another.”

Understanding the essential architectural elements of synagogue design is crucial for architects, designers, and congregations as these elements not only shape the aesthetics but also profoundly impact the communal and spiritual experiences of those within.

This article explores key architectural components essential in synagogue design, illustrating how each influences worship, community cohesion, and Jewish identity.

‍

1. The Aron Kodesh: The Heart of the Synagogue

‍

The most sacred element of any synagogue is undoubtedly the Aron Kodesh, or the Ark, which houses the Torah scrolls. Symbolically and practically, the Aron Kodesh defines synagogue architecture.

According to Rabbi Hayim Halevy Donin in his authoritative work, To Pray as a Jew, the Aron Kodesh must always be placed along the wall facing Jerusalem (the mizrach, east wall, in the Western world):

“Orienting toward Jerusalem ensures a deep spiritual and physical connection to our ancestral homeland, guiding the focus of prayer.”

Architectural Importance:

• Typically designed as an ornate focal point, highlighting Jewish artistry through carving, gilding, mosaic, or embroidery.
  
  
• Often elevated to enhance visibility, emphasizing the Torah’s significance and holiness.
  
  
• Frequently lit by a perpetual lamp, the ner tamid, symbolizing God's eternal presence.
  
  

Impact on Worship & Community:

• Its placement orients the entire congregation toward Jerusalem, creating unity in direction and intent.
  
  
• The centrality visually and spiritually reaffirms the Torah’s place at the heart of Jewish practice and life.
  
  

2. The Bimah: Center of Communal Worship

‍

The bimah is another essential component of synagogue architecture. It’s the raised platform from which the Torah is read, and services are led.

Rabbi Lawrence A. Hoffman, a prominent professor at Hebrew Union College, emphasizes that:

“The bimah is not merely functional—it is deeply symbolic, a place where Torah meets community, and community meets tradition.”

Architectural Importance:

• Traditionally placed centrally (particularly in Orthodox and Sephardi synagogues), ensuring Torah reading and prayers occur within the midst of the congregation.
  
  
• In modern or Reform designs, often situated closer to the Aron Kodesh for practical visibility and acoustics.
  
  

Impact on Worship & Community:

• A central bimah fosters a sense of communal equality, allowing all congregants to feel intimately involved in prayer and reading.
  ‍
• Its elevated position supports clear sightlines and acoustics, critical for communal participation and understanding.

‍

3. The Mechitzah: Balancing Tradition and Community

‍

In Orthodox synagogues, a mechitzah, a partition separating men and women during prayer, is another critical architectural element. Rabbi Joseph B. Soloveitchik, the influential Orthodox theologian, noted:

“A properly designed mechitzah preserves modesty and reverence, enhancing spiritual concentration rather than limiting participation.”

Architectural Importance:

• Often designed with decorative screens, woodwork, or glass to ensure aesthetic beauty without compromising halachic standards.
  
  
• Requires precise attention to sightlines, acoustics, and spatial comfort.
  
  

Impact on Worship & Community:

• When thoughtfully designed, a mechitzah helps create respectful and spiritually focused environments for worshipers of all genders.
  ‍
• Community acceptance often hinges on balancing traditional requirements with modern expectations of inclusivity and participation.

‍

4. Seating Arrangement: Fostering Communal Bonds

‍

Rabbi Elliot Cosgrove, spiritual leader of Park Avenue Synagogue in New York, has written extensively about synagogue seating’s role in fostering community:

“The arrangement of seating should reflect our theological ideals—community, intimacy, equality—and not just practicality.”

Architectural Importance:

• Traditional Orthodox shuls prefer inward-facing seating to encourage collective participation.
  
  
• Conservative and Reform congregations often arrange seats auditorium-style, favoring clear views and acoustics.
  
  

Impact on Worship & Community:

• Seating arrangements deeply influence social interactions, facilitating a sense of communal belonging and mutual responsibility.
  ‍
• Thoughtful design can foster intergenerational connections and communal intimacy, crucial for thriving synagogue communities.

‍

5. Stained Glass and Natural Lighting: Spiritual Symbolism and Atmosphere

‍

Jewish architect and scholar Louis Davidson explains:

“The use of natural and symbolic light is central to synagogue architecture, representing divine presence, hope, and revelation.”

Architectural Importance:

• Stained glass often portrays biblical narratives or Jewish symbolism, enhancing spiritual contemplation.
  
  
• Natural lighting creates an atmosphere conducive to prayer and reflection, symbolizing spiritual illumination.
  
  

Impact on Worship & Community:

• Carefully chosen lighting elements uplift worship experiences, elevating spiritual focus and emotional connection.
  ‍
• The interplay of natural and symbolic light fosters an atmosphere of holiness and tranquility essential for spiritual contemplation.

‍

6. Educational and Social Spaces: Extending Community Beyond Prayer

‍

According to Rabbi Sharon Brous, senior rabbi of IKAR in Los Angeles:

“A synagogue is equally about communal and educational spaces as it is about prayer, shaping the rhythm of communal Jewish life.”

Architectural Importance:

• Classrooms, communal halls, and gathering spaces are crucial elements, ensuring that Jewish education and lifecycle events can seamlessly coexist within the sacred environment.
  
  
• These spaces must balance flexibility with a clear separation from dedicated worship areas.
  
  

Impact on Worship & Community:

• Providing inviting, comfortable communal and educational areas transforms a synagogue into a holistic community hub, integral to daily Jewish living.
  
  
• Thoughtful spatial design encourages informal community interactions, strengthening communal bonds and fostering Jewish continuity.
  
  

Conclusion: Architecture as Sacred and Social Responsibility

The architectural elements discussed—Aron Kodesh, bimah, mechitzah, seating arrangements, lighting, and educational spaces—are not merely structural decisions. They profoundly shape the spiritual and communal life within a synagogue.

Rabbi Abraham Joshua Heschel famously observed:

“The synagogue is a visible manifestation of invisible meaning—an architectural expression of our deepest spiritual aspirations.”

Synagogue design thus represents a unique responsibility and opportunity: architects and communities collaborate not merely to erect buildings, but to cultivate sacred spaces that reflect, sustain, and enrich Jewish life.
