05
The roof is designed for planting greenery, integrating nature into the memorial space.

The Riga Columbarium is located in Latvia's capital city, situated within the vast Forest Cemetery. It offers a thoughtful space for remembrance and reflection. The design features 17 similar modules, each thoughtfully arranged to highlight light and natural elements. This arrangement creates an environment that encourages contemplation and personal connection.

Design Concept

The concept behind the columbarium focuses on the role of light in the act of remembrance. The modules draw inspiration from traditional mausoleums, merging historical references with contemporary design. The layout avoids strict geometrical patterns, opting instead for a more flowing arrangement. This approach fosters an immersive experience, allowing visitors to engage with the space in a meaningful way.

Materials

The columbarium is constructed using stainless steel and concrete. These materials provide structural support while maintaining a clean aesthetic. Each module has a concrete podium and vertical slabs that form niches for urns. Each module contains 30 niches, with each niche designed to hold four urns. This efficient use of space maximizes capacity while allowing light to interact with the surfaces, creating depth and shade.

Lighting and Sustainability

A notable aspect of the design is the use of solar technology, which powers battery-operated lights that turn on based on surrounding light levels. This feature enhances visibility while also emphasizing the importance of light in the memorial experience. Translucent concrete panels filter light, adding warmth and a sense of peace to the space, especially during dusk when shadows play across the surfaces.

Memorialization and Interaction

The columbarium layout includes specific areas for visitors to place flowers and candles in front of the niches. This encourages a personal connection to the site, inviting acts of remembrance and tribute. The roof is designed to accommodate plants, linking the structure to nature. The combination of greenery and light creates a calming environment, especially as the day fades and artificial light mingles with natural twilight.
