In the Swiss village of Mulegns, a futuristic 98-foot (30-meter) tower named Tor Alva (the “White Tower”) stands as a striking contrast to its centuries-old surroundings. Built entirely by robots, it’s the world’s tallest 3D-printed structure—taller than six double-decker buses stacked together. Opened to the public in May 2024, this architectural marvel combines cutting-edge technology with cultural revitalization, aiming to attract tourists and breathe new life into a dwindling community.
A Beacon of Innovation and Culture
Designed by ETH Zurich and the Origen Cultural Foundation, Tor Alva resembles a layered cake—a nod to the region’s confectionery history—and features intricate detailing inspired by filigree metalwork. The tower hosts a 32-seat cupola theater at its peak, offering panoramic views of the Alps for performances starting in July. Giovanni Netzer, Origen’s founder, calls it a “technical triumph” that merges sustainability, culture, and advanced robotics.

Mulegns, once a thriving 19th-century tourism hub, now faces depopulation, with just 12 residents. The tower, a temporary installation set to relocate by 2030, aims to reinvigorate the village through cultural events and global media attention. “Tor Alva is a beacon for sustainable development,” says the project team, emphasizing its role in preserving heritage while embracing innovation.
How It Was Built
The tower’s 32 columns were printed over five months at ETH Zurich’s campus using robotic arms and a specialized concrete mix. The material had to bond quickly enough to support layers but remain pliable for intricate shapes. After printing, components were transported 80 miles to Mulegns and assembled atop a former blacksmith’s workshop. A helicopter removed a protective cover during its grand unveiling, revealing the tower’s ghostly white facade.

Key Stats:
- Height: 98 feet
- Material: 3D-printed concrete
- Cost: ~£880,000
- Capacity: 32 guests in the theater
A Symbol of Architectural Ambition
Tor Alva’s design pushes the boundaries of 3D printing, enabling complex geometries impractical with traditional methods. Experts hail it as a milestone in computational design, blending art and engineering. While costly, it highlights 3D printing’s potential for customizable, waste-reducing construction—a growing trend in addressing housing and infrastructure needs.

The Future of 3D-Printed Construction
As the tower draws visitors, its creators hope to reverse Mulegns’ population decline. By 2030, Tor Alva will be dismantled and rebuilt elsewhere, leaving a legacy of innovation. Meanwhile, 3D printing continues to disrupt architecture, with firms like Mighty Buildings crafting affordable homes and sustainable structures worldwide.
