Santa Cristina de Lena survives as one of the few pre-Romanesque churches in these parts. It has stood since the mid 9th. c. and is worth a small detour to visit.
It has recently undergone a restoration, where even more forgotten carvings (and windows) were revealed. It costs 1€ to get in, and the hours are mixed. However, the caretaker is more than happy to stop by outside of the usual hours if you give her a ring. (985 490 525 or 609 942 153)
The surrounding area is also the best place to picnic or summer nap.
Leaving the church, it is not necessary to retrace your steps back to Vega del Rey. Instead take the path in front of the church. It will descend to a train station where you can cross under the tracks and rejoin the camino.
