Prime Tower

This guide to Prime Tower in Zurich turns on a single frame of security footage from a February evening in 2018, when roughly sixty football fans poured out of the Hardbrucke underpass and rushed the glass base of the tower before a cup match, leaving three men needing hospital treatment. It follows the years-long case through the Zurich district court, and sits that street violence against the tower itself, finished in 2011 on a former precision-gear factory site as a study in engineered calm. Look up at its tilted, eight-sided glass skin, all thirty-six floors of it worked out to the millimetre.
