The Obsidian Rupture is located in the Black Lava Fields of Dimmuborgir, Iceland. It serves as a visitor center designed to reflect the unique geological features and rich cultural stories of the area. Taking its name from the meaning of "Dimmuborgir," which translates to "Dark Castles" or "Dark Cities," the center features a geode-shaped structure that forms a visible connection to the volcanic landscape. The building provides a distinctive experience for both local residents and tourists, blending nature with educational exploration.

Site Integration

The design emphasizes a connection to the surrounding landscape through a carefully planned entrance. Visitors access the main area via a bridge, while a disabled-friendly ramp leads to a lower courtyard. This design encourages movement through the area, allowing visitors to engage directly with the natural environment. The courtyard is framed by concrete walls that have been thoughtfully punctured with openings. These openings reveal the geological layers of the site, enhancing the educational experience for those who visit.

Spatial Organization

Inside the center, the layout reflects ideas associated with volcanic formation. A central staircase connects various levels, leading to exhibition spaces and a café. This vertical journey culminates at a rooftop terrace showcasing views of the nearby Hverfjall Volcano and Myvatn Lake. As visitors explore the different levels, they experience a sense of connection to the landscape, which fosters their understanding of the site’s natural features.

Materiality and Sustainability

The center is clad in polished basalt panels that align with the local landscape. This choice in materials enhances the connection between the structure and its environment. In addition, geothermal energy systems provide heating and cooling for the building, while solar tiles on the roof contribute to its energy efficiency. The use of soil excavated from the site in the construction minimizes environmental impact, positioning the center as part of the local setting.

Natural Light and Views

Natural light is a significant aspect of the design. The carefully placed openings in the walls allow sunlight to enter the interior. This illumination creates a warm atmosphere while providing visitors with views of the surrounding environment. As they move through the building, visitors are constantly reminded of the historical and geological context of Dimmuborgir, resulting in a lasting connection to the landscape.
