Rua 24 Horas, Shopping gallery in central Curitiba, Brazil

Rua 24 Horas is a covered commercial street in central Curitiba, 120 metres long and 12 metres wide, roofed by 32 arches. It was designed by architects Abrão Assad, Célia Bim and Simone Soares and opened in 1991 with 34 shops. Two large illuminated clocks, one on each facade, show the time in 24 intervals instead of 12.

Rua 24 Horas was inaugurated in September 1991 by mayor Jaime Lerner, with 34 shops open around the clock. It closed in 2007 and, after failed private partnerships, the city began revitalization works in July 2010. The street reopened on 11 November 2011 at 11 AM, at a cost of 4.1 million.

The name comes from the original 24-hour operation of its 34 shops, a concept launched by mayor Jaime Lerner in 1991. Two large clocks, one on each facade, show the hours in 24 intervals instead of 12, lit and driven by a quartz electronic control. Since the 2011 reopening, opening hours run from 9:00 AM to 10:00 PM.

The passage runs 120 metres between two central Curitiba streets, with entrances at each end marked by large clocks. Since reopening in 2011, opening hours are limited to 9:00 AM to 10:00 PM, so it is no longer a night-time route. Check individual shops before a specific errand.

Large illuminated clocks at both passage entrances display time in 24-hour format, controlled by a central electronic quartz system. These distinctive timepieces are a recognizable feature that reinforces the place's name and concept.
