The Trident Columbarium
Architectural Excellence Meets Cremation Planning
Our most recent revision of this model was unveiled in Miami, Oklahoma in 2025. This black and grey Trident model highlighted in the photo above is a 120- niche columbarium composed of three curved niche walls that converge at a single junction, creating a dynamic, triadic form. At the central core of this design lies an integrated ossuary, offering a thoughtful and dignified option for communal interment within the columbarium monument.
Standard Features
Granite Finishes
Premium Materials for Long-Term Durability. The Trident columbarium is constructed using premium-grade granite, selected for its strength, beauty, and resilience. Designed to endure the elements with minimal maintenance, the Trident offers both elegance and long-term reliability.
Custom Features
Customization Options to Fit Your Design Needs.Our engineering expertise enables us to customize any Trident columbarium to meet the specific needs of clients across the country. We tailor each design to fit your unique space, style, and budget.
The Segretto Ossuary:
A Hidden Core for Communal Cremation Remains. Built into the heart of The Trident is the Segretto Ossuary, a secure, concealed space designed for communal cremation interments. The word Segretto means “secret” in Italian — fitting for this beautifully integrated, unseen feature.
Designed With Purpose: Spacious, Safe, and Scalable
Each cremation niche is deep enough to accommodate two upright urns, offering families a companion interment option. The powder-coated niche interiors also prevent metal urns from fusing to the niche interior over time — an essential feature to allow for companion urns to be repositioned further back when needed.
Need more space? The Trident’s modular design can be expanded in height or length, with additional niche rows or architectural elements. Custom niche sizes are also available.
Memorial Wall for Names & Legacy
Adjacent to The Trident is a custom Memorial Wall, constructed from matching granite. It serves as a record of namesfor individuals interred in the ossuary or elsewhere on-site. This feature offers an additional revenue stream for cemetery managers while enhancing the emotional impact of the space. If preferred, we can also design a custom memorial wall that seamlessly aligns with your landscape’s aesthetic.
