Overview

• Tor Alva stands 98 feet tall with 32 intricately printed concrete columns inspired by local filigree and confectionery traditions.
• Each column was 3D-printed over five months at ETH Zurich’s Hönggerberg campus before transport and assembly in Mulegns on May 20.
• A cupola theatre crowns the tower and will host staged performances starting July 2025 to attract visitors and enliven the village.
• The project uses a custom concrete mix developed by ETH Zurich to achieve complex shapes with minimal material waste.
• Designed as a temporary installation, Tor Alva will be dismantled and rebuilt at a new location in 2030 to replicate its revitalizing impact.
