Vortex: Architecture of the Circle
Author Philip Jodidio

A study of the striking Vortex building in Lausanne, Switzerland, a powerful reflection of circles in architecture.

Edited and authored by the renowned architecture expert Philip Jodidio, this book is dedicated to a new, eye-catching building by Swiss architect Jean-Pierre Dürig located in Lausanne, also known as the “Olympic Capital.” As the structure’s name suggests, Vortex is an 88-foot-high tower in the shape of a cylinder, rising around a single, continuous 1.7-mile-long ramp. Its spiraling movement creates an emblematic shape reminiscent of Olympic rings—a fitting tribute for a building that housed the 1,700 talented young athletes who competed in the Winter Youth Olympic Games in January 2020.

Over 130 photographs, sketches, plans, and models illuminate this enormous undertaking, while Jodidio’s informative text offers detailed insight into the phases of design and construction. Imagery of circular references from art, architecture, and nature highlight the inspiration behind the building’s extraordinary shape. Printed in Italy using the finest European papers, this volume is a beautiful ode to Vortex and Lausanne’s forward-looking spirit.

YOG – Lausanne 2020; Report: ‘The carbon footprint of the 2020 Winter Youth Olympics’

The Lausanne 2020 Organizing Committee partnered with Quantis to conduct a carbon footprint assessment of the 2020 Winter Youth Olympic Games. It was the first such assessment to follow the Carbon Footprint Methodology Guidance of the IOC. The aim of the assessment was to understand the impact and effectiveness of the organizational and policy measures taken and to leave a legacy for future Organizing Committees in developing their sustainability action plans to measure and minimise their events’ greenhouse gas emissions.

YOG – Lausanne 2020; Press release: ‘Lausanne 2020: a popular and financial success’

The Lausanne 2020 Youth Olympic Games (YOG) came to a close almost five months ago to the day. This presented an opportunity for the Organising Committee to look back on the great sporting and popular success of the YOG as well as the positive financial results. Now, it’s time to look at the legacy, which will be managed by a new structure set up for this purpose.

The Lausanne 2020 Organising committee today gave the media one last rendezvous, five months after the closure of the YOG and the day after its official dissolution. This was an opportunity to bid farewell to the public and to present the various results of the event.
