Bubas Bridge, Colonial bridge in Puebla, Mexico.
Bubas Bridge is a stone passage from colonial times that connects the western part of Puebla with the city center, running beneath the present-day streets. The structure was buried for centuries when the San Francisco riverbed was vaulted over, but it was uncovered and restored in 2014 and is now open to visitors.
The bridge was built in 1555 on the orders of corregidor Don Luis de León Romano to enable crossing over the San Francisco River. This project marked one of the earliest major infrastructure efforts in the developing colonial city.
The structure is featured in a local tour circuit that highlights underground passages and colonial craftsmanship, offering insight into how the city was built and connected in its early years.
Access is typically through guided tours that lead visitors through the underground chambers and explain the layout and structure. Wear comfortable shoes, as the ground can be uneven and the passages have tight spots that require careful navigation.
What makes this passage notable is that it is among the oldest known infrastructure projects in Mexico, showing how early colonial planners designed river crossings. Its rediscovery after centuries of being lost stands as a rare example of urban archaeology that restored a hidden part of the city's past.
