The Iceland Cave Tower is a visitor center located near the Grjótagjá caves by Lake Mývatn in Northern Iceland. Designed to increase visitor access and enhance their experience, the tower embraces a concept centered on exploration that connects with the region's natural features. The architecture reflects the unique geological landscape and creates an inviting space for tourists looking to immerse themselves in this captivating environment.

Site Integration

The tower’s form resembles a sharp, crystalline structure that rises upward, acting as a landmark for those approaching. This design mirrors the geological formations found in the Grjótagjá caves, establishing a connection between the building and its natural surroundings. When visitors step inside, they enter a grand hall that evokes the feeling of being in a cavern. This design choice effectively sets the stage for an adventure into the landscape.

Functional Layout

The layout of the building is organized to facilitate a smooth flow of visitors. On the ground floor, there is a spacious hall, which can host small exhibitions and serves as a waiting area for tourists before exploring the caves. Essential facilities, including restrooms, an office, and a technical room, are conveniently arranged to meet visitors' needs. The technical room holds mechanical systems that extract heat from the ground, ensuring a comfortable environment throughout the year.

Visitor Experience

On the next level, visitors will find a cafeteria that offers hot and cold beverages, adding to their overall experience. A first observatory floor provides beautiful views of the surrounding area, with an elevator making it accessible for all. An upper observatory area allows for a 360-degree view, showcasing the tectonic border between the Eurasian and American plates, an important geological feature of the region.

Material Selection

The Iceland Cave Tower uses a lightweight steel framework and volcanic stone cladding tiles. These materials help the building blend into its geological context while supporting sustainable practices. The rich tones and textures of the volcanic stone also reflect the area's identity and enhance the overall appearance of the structure.

The tower has dark walls on the ground floor, allowing natural light to enter from above, creating an atmosphere similar to being within a cave. The high ceilings of the entrance hall give it a dramatic feel, resembling an ancient underground chamber. This design enriches the visitor's experience, encouraging a deeper connection with the fascinating characteristics of the Grjótagjá caves.
