The Iglesia de San Estaban and its adjacent ruined tower are at the summit of Sos. The gothic church, with its 13th century frescos in the crypt are worth a visit. The crypt (entry 1 euro) is accessed down a very steep spiral staircase.
This small bar and restaurant (Asador) is in the midst of old Sos.
It has a restaurant upstair, but we ate raciones of sausages in the bar. The bar is a pleasant, small, typical vallage establishment.
Favorite Dish: Sausages!
If you are travelling to Sos by car, take a drive around on some of the minor roads. The lack of traffic and outstanding views make this an interesting experience.
