No Stone Tombstone is a next-generation death care and memorialization infrastructure designed as a core solution within the Sim Eternal City Framework. It responds to three converging pressures facing contemporary cities: climate change, urban spatial scarcity, and demographic aging.
As part of the Sim Eternal City Framework, No Stone Tombstone functions simultaneously as:
A business model to operate the floating city for elderly citizens
A solution to land city’s cemetery shortage
A next-generation death-care and memorialization system
And a memory infrastructure connected to the Life Tree Nexus and the 18-Minute City rhythm
It replaces the heavy, space-consuming logic of “stone tombstones” with a light, mobile, distributed, and data-connected memorial ecosystem.
Traditional cemeteries and funeral infrastructures are no longer compatible with dense, climate-vulnerable, and longevity-driven urban environments. They permanently consume land, are difficult to relocate, and are poorly integrated with modern urban life and digital memory systems.
No Stone Tombstone proposes a distributed, mobile, and data-integrated memorial ecosystem that transforms death care from a land-intensive, static system into a city-scale, adaptive, and sustainable civic infrastructure.
This system is composed of three integrated components:
Island Park Cemetery (Floating, productive memorial zone)
Dolmen City Cemetery (Distributed urban kiosks + home memorial devices)
SIM Eternal Ceremony Vehicle (Mobile healthcare + death-care integrated service)
Together, these components connect physical remembrance, digital memory, and urban operations through the Life Tree Nexus and the 18-Minute City (15+3) framework of Sim Eternal City.
1. Problem Definition: The Structural Limits of Contemporary Death Care
1.1 Spatial Unsustainability
Urban cemeteries occupy large, permanently locked land areas.
In high-density cities, new cemetery development is politically, economically, and spatially infeasible.
Many existing cemeteries are located in climate-vulnerable zones, especially in coastal cities.
1.2 Demographic Pressure
Aging societies increase the long-term demand for death-care infrastructure.
Existing systems scale only by consuming more land and resources.
1.3 Institutional Inflexibility
Funeral homes, cemeteries, and religious facilities are fixed, heavy infrastructures.
They do not adapt well to compact cities, mobile populations, or digital cultural practices.
1.4 Disconnection from Digital Memory
Current death-care systems fail to integrate:
Personal data
Life records
Family archives
Civic memory systems
Memory remains fragmented, fragile, and often lost over generations.
2. Strategic Vision: From “Stone” to “System”
No Stone Tombstone reframes death care as A light, distributed, mobile, and data-connected urban service layer, rather than a static land-consuming facility.
The core shift is:
From permanent physical occupation → to managed temporal and digital continuity
From isolated burial sites → to networked memory infrastructure
From single-event ceremonies → to long-term memory stewardship
This approach aligns death care with:
Climate adaptation strategies
Urban densification realities
Digital civilization and memory preservation
The longevity economy and care infrastructure
3. System Architecture

New funeral homes are difficult or impossible to build
Large ceremonial facilities are spatially inefficient
End-of-life care must be flexible, accessible, and human-centered
Key features:
Mobile, city-scale deployable unit
Integrates:
End-of-life care
Funeral ceremony
Family gathering
Memory documentation
Data transfer to Life Tree Nexus
Strategic value:
Replaces heavy, fixed death-care infrastructure with adaptive service mobility
Creates a new category of urban death-care service
Bridges healthcare, care economy, and memorial infrastructure
Mobility based Sim Eternal Funeral Ceremony Service
4. The Second Funeral & Virtual Cemetery Transition
No Stone Tombstone introduces a Two-Phase Memorial Model that redefines how cities manage memory, land, and continuity over time.
Phase 1: Physical Memorialization
In the first phase, memorialization takes place through Island Park Cemetery and other managed physical memorial sites within the Sim Eternal City system.
This phase preserves the cultural, emotional, and ritual importance of physical remembrance, while integrating care, curation, and archiving into a living civic landscape.
Phase 2: Second Funeral & Virtual Cemetery Transition
After a defined period (e.g., 10 years), a Second Funeral Ceremony is held.
This ceremony marks the transition of the memorial from a physical site to a virtual cemetery connected to the Life Tree Nexus.
This transition does not signify erasure or loss. Instead, it represents a shift of remembrance:
From land-based permanence
To system-based continuity through digital memory, archiving, and civic access
Key Outcomes
Releases physical space previously locked by permanent graves
Maintains emotional and cultural continuity through ritual, data, and shared memory systems
Establishes a sustainable temporal cycle of memory management, instead of infinite spatial expansion of cemeteries
4.1 Urban Transformation: From Cemeteries to Public Housing
A critical implication of the No Stone Tombstone model is its urban land recovery strategy.
By gradually relocating and transitioning land-city physical cemeteries into the No Stone Tombstone system:
Large, land-intensive cemetery sites in land cities can be systematically freed
This reclaimed land can be redeveloped into public housing and civic infrastructure
As a result:
Cities can address housing shortages
Land city citizens can gain access to affordable homes
Even the urban homeless population can be reintegrated into the housing system
In this sense, No Stone Tombstone is not only a death-care innovation, but also: A climate-adaptive, socially inclusive urban regeneration mechanism that converts the legacy land use of cemeteries into future-oriented public housing and civic space.
4.2 From Spatial Expansion to Temporal Management
Traditional cemetery systems solve demand by expanding in space—consuming more land indefinitely.
No Stone Tombstone replaces this logic with temporal management of memory:
Memory is preserved through:
Ritual transitions
Digital archiving
The Life Tree Nexus system
Physical land is:
Used responsibly
Recycled back into the urban fabric
Reallocated to urgent civic needs such as housing
This establishes a sustainable, cyclical model where:
Cities do not grow cemeteries forever
But instead circulate memory through systems and time
5. Integration with Life Tree Nexus and the 18-Minute City
In the Sim Eternal City Framework:
The 18-Minute City (15+3) model defines:
15 minutes for daily life infrastructure
3 minutes for memory, recording, education, and transmission
No Stone Tombstone is the primary civic infrastructure expression of the 3-minute layer.
Dolmen Kiosks & Home Devices: daily memory input
Ceremony Vehicles: life-to-death transition capture
Island Park Cemetery: physical memory landscape
Life Tree Nexus: long-term archiving, indexing, and access layer
Together, they form a city-scale memory and continuity system.
