Karavanke tunnel – second tube

The new design of the Karavanke portal draws inspiration from the architecture of Savin Sever, one of Slovenia’s most prominent architects of the 20th century. Sever’s work is distinguished by its structural and functional approach to architectural challenges, a hallmark of his enduring legacy. This project represents the reconstruction and reinterpretation of an unfinished project by the architect Savin Sever. He received the national Plečnik medal award in 1989, for special sensitivity in the placing of a big infrastructural object into the delicate Alpine environment. In honoring this tradition, the design reflects a comprehensive treatment of space while maintaining a sense of continuity between the past and present. By interpreting the existing architectural elements through the lens of contemporary design, the conceptual foundation remains consistent with its historical roots. The portal building serves as an entry point to the mountain and a symbolic gateway to the country. The new spatial volume respects the original form and dimensions, preserving the integrity of the dual-volume concept while adapting it to contemporary needs. The façade is envisioned as a transparent membrane, integrating the technology necessary for the tunnel’s functionality. While the functional baseline has evolved, the design remains grounded in Sever’s philosophy. This shift necessitates reevaluating the initial design premise. Where “form follows function” once defined the approach, the new guiding principle is “form follows the symbol,” reflecting a deeper connection to the portal’s symbolic significance.
