Summary

A 6-minute walk from Casa Antiguo Domingo leads you to one of Casco Viejo’s most remarkable architectural relics: Arco Chato, or the Flat Arch. This seemingly gravity-defying structure is a remnant of the Church and Convent of Santo Domingo, dating back to the 17th century. The arch earned international attention for standing unsupported for over 300 years—a feat of colonial engineering that helped influence the decision to build the Panama Canal through Panama instead of Nicaragua.

The site, though modest in size, is incredibly atmospheric. Crumbling stone walls, moss-covered remains, and the open sky above create a raw and historic aesthetic that’s perfect for quiet reflection or photography. Arco Chato stands as a powerful symbol of resilience and ingenuity in Panama's story.

It’s also centrally located, tucked just behind a small plaza that sometimes features local artisans and food vendors. Visitors often stop here as part of a broader walking tour through Casco’s religious and colonial landmarks. If you're intrigued by architecture, engineering, or lesser-known bits of history, Arco Chato is a site you won’t want to miss—and it's close enough for a spontaneous visit during your stay.
