A LOST MASTERPIECE OF LOG ARCHITECTURE: THE GRAND TIMBER TEMPLE OF OREGON
Imagine stepping into a vast structure where the very walls and columns are carved from massive tree trunks, their earthy scent mingling with sunlight filtering through timber arches. This wasn’t a fantasy—it was a reality in 1905 Portland, Oregon. Known as the Forestry Building, this grand structure was once dubbed “the world’s largest log cabin,” and rightfully so. Built for the Lewis and Clark Centennial Exposition, it stood as a proud testament to the Pacific Northwest’s rich forestry heritage.
Though the structure was tragically lost to a fire in 1964, its legacy endures in old photographs, museum records, and the memory of a community that once marveled at its scale and symbolism. This article explores the story of this extraordinary building—from its construction to its destruction—and the legacy it left behind.
Historical Context: Born from an Exposition of Discovery
The Forestry Building was constructed as part of the Lewis and Clark Centennial Exposition, held in Portland in 1905. This world’s fair-like event celebrated the 100th anniversary of the Lewis and Clark expedition and showcased the economic and natural wealth of the American West, particularly Oregon.
Among the key attractions of the exposition, the Forestry Building quickly gained fame for its architectural audacity and aesthetic brilliance. It was designed not just as a display hall, but as a symbol of Oregon’s booming timber industry, which was already emerging as a pillar of the state's economy.
The Exposition was a moment of pride and a declaration of potential. For Oregon, the Forestry Building wasn’t just a pavilion—it was a temple of timber, meant to awe, inspire, and attract national attention.
Architectural Marvel: Engineering Nature into Grandeur
The Forestry Building’s design was both a technical feat and an artistic expression. Constructed mainly from Douglas fir, the structure featured massive logs—some measuring over 6 feet in diameter and 54 feet in length. These immense logs were left in their natural, unpeeled state, creating a rustic yet majestic appearance.
Architect Ion Lewis, of the firm Whidden & Lewis, masterminded the building’s design. With 68 colossal log columns supporting a log truss roof, the interior felt more like a natural cathedral than an exhibition hall. Its cathedral-like interior featured arched beams, a high vaulted ceiling, and wide open spaces where nature met craftsmanship.
The design achieved something rare: it blended seamlessly into the surrounding forest, embodying a vision of architecture that complemented the environment rather than imposing upon it. The building's log facade and wooden walkways reinforced the immersive experience of being one with the forest.
Interior Exhibits: Celebrating Forestry as Art and Industry
Inside, the Forestry Building served a dual purpose. On one hand, it was a museum, filled with exhibits on the region’s forest resources—including giant logs, polished cross-sections of tree trunks, and handcrafted wooden furniture. On the other, it was a living showcase of sustainable industry and natural craftsmanship.
Every exhibit was a tribute to Oregon’s timber legacy. Visitors could examine the grain patterns of exotic wood types, view hand tools used by early loggers, or admire detailed carvings and joinery. These weren’t just static displays—they told a story of how nature, labor, and art intersected in the timber-rich Northwest.
Even the flooring and furniture echoed this theme, with custom wooden benches, information desks, and decorative installations—all crafted from locally sourced wood.
Tragic End: The Fire That Consumed a Wooden Wonder
After standing proudly for nearly six decades, the Forestry Building met a heartbreaking end on the night of August 17, 1964. A devastating fire broke out and quickly engulfed the entirely wooden structure. Despite firefighting efforts, the building burned to the ground, leaving nothing but ashes and charred foundations.
The fire was believed to have been caused by faulty electrical wiring, although no definitive cause was ever confirmed. The wooden logs, aged and untreated by modern fire-retardants, fueled the flames like kindling. Within hours, a national architectural treasure was lost forever.
For Portland and Oregon residents, the loss was deeply emotional. The building was more than just wood and nails—it was a symbol of the region’s natural identity, its historical ingenuity, and its artistic craftsmanship. News reports from that time noted that “an irreplaceable piece of Oregon’s history had vanished overnight.”
Legacy and Remembrance: Preserving a Timber Icon in Memory
Though the Forestry Building no longer stands, its memory lives on through a handful of photographs, architectural drawings, and records archived in Portland’s museums and libraries. Institutions such as the Oregon Historical Society and Portland State University have preserved black-and-white images that capture the structure’s former grandeur.
In honor of the original, a new facility—the World Forestry Center Discovery Museum—was built in 1971 near the original location in Washington Park, Portland. While not a replica, this modern museum continues the mission of educating the public about forestry, sustainability, and Oregon’s natural resources. It serves as both a tribute and a continuation of the values the Forestry Building once represented.
A bronze plaque now stands near the museum site, marking the legacy of the lost building and reminding visitors of the importance of preserving both cultural heritage and natural beauty.
Modern Applications and Research: The Return of Timber in Architecture
Interestingly, the spirit of the Forestry Building has found new life in modern architecture and environmental design. The use of timber, once seen as outdated, has seen a revival through mass timber construction and cross-laminated timber (CLT) technologies.
In fact, Oregon has remained a leader in this space. Projects like Carbon12, an 8-story residential building in Portland completed in 2018, is one of the tallest mass timber buildings in the United States. Designed by PATH Architecture, the building highlights how sustainability and wood engineering can coexist beautifully in urban environments.
Globally, countries like Norway, Japan, and Canada have embraced timber in ambitious ways. The Mjøstårnet building in Brumunddal, Norway—completed in 2019—currently holds the record as the world’s tallest timber building, standing at 85.4 meters (18 stories). It was built using sustainable glulam (glued laminated timber) and CLT, showing the future potential of wood in safe, eco-friendly high-rise architecture.
Moreover, architectural studies have referenced the Forestry Building as an early inspiration for biophilic design principles—an approach that integrates natural materials and environments into built spaces to improve well-being and connection to nature.
Research institutions such as the TallWood Design Institute (Oregon State University + University of Oregon) continue to explore innovations in timber engineering, seismic resilience, and fire safety—directly addressing the kinds of vulnerabilities that led to the Forestry Building’s tragic end.
Lessons from the Past: What the Forestry Building Still Teaches Us
The story of the Forestry Building is more than just a nostalgic glance at a lost structure—it's a lesson in vision, craftsmanship, sustainability, and the risks of neglecting preservation. At its core, the building was a pioneer in promoting eco-conscious design long before environmentalism became a global priority.
Its destruction reminds us of the fragility of heritage architecture, especially when safety protocols and modernization are overlooked. Had it been preserved and retrofitted with fire prevention systems, it might still be standing today as a global example of early 20th-century log construction.
The building also offers lessons for modern designers and architects: natural materials can be used to create monumental beauty without compromising on function. But it also teaches that innovation must be balanced with safety, maintenance, and adaptability.
