Bridge of Mantible, Ancient stone bridge ruins in Logroño and Lanciego, Spain.
The Bridge of Mantible is a stone crossing over the Ebro River between Logroño and Lanciego with surviving medieval arches still visible today. The structure features a sloped roadbed designed to accommodate varying water levels and displays multiple arch openings of different sizes.
The structure was built in the 11th century under King Sancho Garcés III, contrary to earlier assumptions about its Roman origins. The bridge demonstrates medieval engineering and the political importance of this river crossing in the region.
The bridge served as a vital crossing for pilgrims journeying to Santiago de Compostela and continues to shape how locals view their landscape. People today recognize it as a regional landmark and evidence of medieval connections between communities.
Access is available from both sides of the river: from the El Cortijo neighborhood in Logroño or via marked paths from Lanciego. Wear sturdy footwear since the riverbanks are uneven in places and the paths follow the water's edge.
The structure is notable for its ingeniously sloped deck that adapts to varying shore elevations, which is why the arches differ in height. This design allowed medieval builders to create a stable crossing despite the challenging terrain on both sides.
