because it is so close to the Castillian frontier, as well as along the Camino, Los Arcos became a toll-collecting station and place to change money. in the 12th century, the king authorized weekly markets and equalized rights between locals and immigrant Francos in an effort to encourage growth of the town. the proximity to Castilla also made it a frequent military target.
the town’s location — on a river with a hill overlooking and farmland spreading out — means it has likely been inhabited since Roman times. a castle protected the city on a hill to the northeast of the city beginning in the 12th century, but that didn’t stop Castilla and Navarra from periodically annexing and/or taking the town by force over the course of the next three hundred years. as elsewhere in the region, the Napoleonic and Carlist wars took their toll on the town, which played host to two battles during the first Carlist War (the one launched from Estella, some 20 kilometers away).
Los Arcos had a tidy, compact plaza in front of the Iglesia de Santa Maria where we enjoyed our afternoon restorative cervezas and, once the kitchen reopened, dinner. construction of the church occurred over six centuries, beginning around 1175. consequently the interior offers an array of decorative and architectural styles including Flamboyant and Flemish Gothic, Baroque, Mannerism, Churrigueresque, and Rococo. beyond the far end of the plaza is the Arco de Felipe V, the last remnant of the defensive system that protected Los Arcos from the 18th onwards.
