Sansol is a small hilltop village that the arrows rush you through along the road. To see anything of interest — the church, the old baroque houses with their carved facades, and what remains of the village center — turn right at the ceramic tile sign at the entrance.
A small shop and a bar with a terrace near the Palacio albergue make this a reasonable place for a quick stop. The views from the upper village over the surrounding countryside are good.
Named after San Zoilo, a young man martyred in Córdoba under Diocletian in 304. His relics ended up in the Benedictine Monasterio de San Zoilo in Carrión de los Condes, which you'll reach in a few weeks. The parish church here is also dedicated to him.
The descent from Sansol to Torres del Río is steep and short. You'll wonder why anyone built a town at the bottom of a valley with so little defensive advantage — the answer is the Río Linares and easy access to water.
