Quevedo and Cossio's Manor House · Santillana del Mar (EN)

It is located in the street of the River in front of the trough or washhouse. It is actually two houses (which are now one), and attached to each other forming a square, built in the late seventeenth century. The most outstanding feature of the building, in addition to the ashlar masonry, is the tunnel with stone arches that crosses the building to serve as a drainage to the trough and stream, from which the street takes its name.
