05
Burnt wood cladding visually connects the building to its volcanic surroundings while ensuring weather resistance.

The Dark Castle is a visitor center located in the black lava fields of Dimmuborgir, designed to connect with the unique geological characteristics shaped by the eruption of the Hverfjall volcano over two thousand three hundred years ago. The center aims to provide educational experiences while allowing visitors to immerse themselves in the natural environment. The overall design considers the landscape's features, creating a harmonious relationship between the building and its surroundings.

Design Concept

The concept centers around a curvilinear form that mirrors the area's volcanic activity. The building's circular layout encourages movement through different functional areas, such as the reception, exhibition spaces, café, and playground. This arrangement makes it easy for visitors to navigate and engage with the exhibits that showcase the geological significance of the region.

Architectural Features

Central to the design is a courtyard, which serves as a gathering space for visitors. It features an installation that mimics the appearance of lava eruptions, linking the experience to the site's volcanic history. The large roof, which measures 45 meters in diameter, acts as both a protective cover and an observation deck. From here, visitors can see the expansive lava fields and nearby lake, enhancing their connection to the environment.

Structural and Material Components

The roof is constructed with cross-laminated timber, providing a sturdy and sustainable structure. This material choice reflects a focus on durability while minimizing environmental impact. The outer layer of burnt wood helps to blend the building with the surrounding landscape and offers resilience against weather conditions. Large windows allow ample natural light inside, framing views of the remarkable scenery outside.

Visitor Circulation

The pathway leading from a drop-off roundabout to the entrance is designed to guide visitors thoughtfully. This winding route helps them engage with the area as they approach the building. Inside, spaces flow together, featuring customized furniture that fits the curves of the architecture. This design creates an inviting atmosphere and encourages exploration of the center's offerings.

Within the design of The Dark Castle, there is a respectful nod to the geological stories of Dimmuborgir. The combination of large windows, wood elements, and an observation deck fosters a clear connection between the internal space and the surrounding natural landscape.
