Zion Lutheran Church, a celebrated architectural gem in Portland, is set to commemorate its 75th anniversary on May 3 with a free organ recital and an open house, showcasing its remarkable design and history.
Designed by renowned Oregon architect Pietro Belluschi, Zion Lutheran Church is recognized as Portland’s first modern sacred space, capturing attention for its striking copper-clad spire and innovative design features.
The celebratory event will run from 2 to 3 p.m. and will include presentations highlighting the timeless architecture crafted by Belluschi, one of Oregon’s most revered architects.
When the church was dedicated in May 1950, approximately 7,000 people attended the event, walking through its unique copper entrance doors to explore the vaulted interior, located in the Goose Hollow neighborhood of Southwest Portland.
Belluschi designed the church with thoughtful architectural elements, including a courtyard and sheltered porch to create a contemplative transition from the street to the sanctuary.
Inside, attendees will notice the elegant beauty of ten pointed arches rising 38 feet to support the roof, while natural light pours through a stunning wall of amber, rose, violet, and clear glass panes, illuminating the copper altar.
Throughout his career, which ended in 1994 shortly before his passing at age 94, Belluschi designed a total of 42 modern, light-filled churches and synagogues across Oregon and the United States.
Nicole Possert, executive director of the preservation organization Restore Oregon, remarked, “Zion Lutheran is considered one of Pietro Belluschi’s finest ecclesiastical designs while also being technologically innovative.”
She noted Belluschi’s minimal ornamentation, focusing on structure and function, creates an immersive acoustical experience, earning the church an esteemed listing in the National Register of Historic Places.
The church’s history dates back to 1889 when members of Portland’s Zion Church purchased property at Southwest 18th Avenue and Salmon Street.
The following year, they built a white clapboard Gothic Revival church, recognizable by its prominent steeple and pointed-arch windows.
In the 1940s, as Lutheran congregations began to emphasize singing and congregational responses in their services, the Portland congregation sought to expand their place of worship.
The plan called for a modern sanctuary with a capacity for 400 people in the nave and 50 in the choir loft, accompanied by a two-story parish hall and an education wing on their half-block-long lot.
They turned to Belluschi, a pioneer of Northwest modernism, who suggested a simpler design and the use of natural materials like Douglas fir, rose-colored brick, and glass to reflect a broader world perspective.
The church’s construction, carried out by the C.M. Corkum Company, commenced in May 1949, and was completed the following year, marking a significant moment in architectural history.
Belluschi’s innovative use of 10-inch hollow glass blocks earned the title of the first “windowless nave” in the United States, allowing for both luminescence and cost-effectiveness.
Additionally, the introduction of freestanding glued laminated timber arches was a groundbreaking technique in church design at the time.
During the dedication ceremony on May 14, 1950, Belluschi emphasized that the Zion Lutheran congregation demonstrated the possibility of achieving emotional fulfillment through modern architecture, without resorting to traditional styles.
He described the church as a “human and gracious environment” free from “pompously designed monuments” or “tricks.”
Today, architectural enthusiasts continue to visit Zion Church, recognized as one of Belluschi’s signature buildings that inspires awe among first-time visitors.
Historian Ruth Hyde wrote that the sanctuary holds a unique ability to “surprise and awaken a response” in unsuspecting visitors, further emphasizing its profound impact.
Belluschi’s artistry extended beyond the structure itself; he also designed furnishings, including a copper-clad altar, an eight-sided baptismal font, and a 19-foot-tall cross.
Additionally, elements such as the pulpit, oak kneeling desk, brass candelabra, and flower stands were meticulously crafted under his guidance.
The church’s front doors feature a sculpted scene of an ascending angel, crafted from copper sheeting by artist Frederic Littman.
Although religious buildings were a modest portion of Belluschi’s extensive career, he found significant artistic fulfillment and expression in ecclesiastical architecture, according to his son, Portland architect Anthony Belluschi.
At the anniversary event, Anthony Belluschi will discuss his father’s passion for church architecture and his ability to inspire the Zion congregation to embrace a forward-thinking approach rooted in elegance and simplicity.
This architectural philosophy emphasized “light, space, texture, and color,” while preserving essential traditional symbols.
Zion Lutheran Church remains highly regarded for its exceptional acoustics, making a notable contribution to its musical heritage.
As noted on the church’s website, the space is known for fostering a rich musical environment supported by its choir and the Martin Ott Opus 104 organ.
Florence Berentsen will perform at the organ recital during the anniversary event, alongside her husband, Kurt, who have been integral to the church’s music ministry since 2007.
According to Kurt Berentsen, the church’s classical worship style is greatly enhanced by its architectural acuteness regarding acoustics.
In this space, only the spoken word is artificially amplified, while voice and organ music, along with congregational responses, depend solely on Belluschi’s careful acoustic engineering—a true art form that enriches auditory experiences for all attendees.
The result is an uplifting environment where singers—whether part of the choir or congregants—feel motivated by the harmonious blend of voices surrounding them.
Belluschi designed the nave with specific dimensions and materials to create the ideal acoustical balance, allowing music’s reverberation to linger in the space “as if they have a life of their own.”
His innovative design included grooved Douglas fir on the ceiling and rear wall and various techniques to enhance sound diffusion and reduce echo, ensuring the sanctuary remains a venue for high-quality musical experiences.
Upon reflecting on his father’s approach to acoustics in design, Marti Belluschi, daughter-in-law of Pietro Belluschi, confirmed that he routinely collaborated with top acoustical consultants for his churches and concert halls, earning praise for their sound quality.
Anthony Belluschi shared that his father was greatly influenced by classical music, often listening to albums while working on architectural projects.
During the open house on May 3, original blueprints of Zion Lutheran Church and other historical memorabilia will be on display, alongside enriching talks led by Pastor Jim Pressnell and architect congregant Brian Fleener, offering further insights into the congregation’s appreciation for their architectural treasure.
