On the streets of Bixiga, anyone walking past the site where the Vai-Vai samba school once stood now finds silent bulldozers and only a few workers on patrol. Instead of heavy machinery and dust, the construction site in central São Paulo looks more like a quiet storage yard for steel and building materials.

The pause comes down to history beneath the pavement. Excavation work on the future 14 Bis-Saracura station on Line 6-Orange of the São Paulo Metro has been suspended indefinitely. The shutdown followed the discovery of new archaeological remains tied to religious practices of African heritage and the historic Quilombo Saracura, an urban settlement formed by formerly enslaved people, according to Folha de S.Paulo.

Artifacts found two meters deep

Specialists from archaeological consultancy A Lasca, hired to oversee the site, uncovered the artifacts 2.2 meters below ground. Inside a buried room, the team found small mounds of indigo powder, tied bundles of twigs, and other ritual items commonly used in Afro-Brazilian religious traditions.

What commuters and residents need to know:

• Work suspended: All digging and heavy construction across the 14 Bis-Saracura site are completely paused.
• Timeline: There is no official date for work to restart at this specific location.
• Line 6 progress: While other parts of Line 6-Orange have started partial operations, the Bixiga station remains on hold.

Waiting for heritage authorities

Concessionaire Linha Uni, led by Spanish infrastructure firm Acciona, is responsible for building and operating the line. The consortium confirmed the full stoppage and stated that it is waiting for guidelines from Iphan, Brazil's national historical and artistic heritage institute, to determine how to protect the artifacts before rescheduling construction work. Iphan received the technical archaeological report in late July and is reviewing conservation requirements.
