Palencia

Crossing the Puente Fitero brings you into the province of Palencia.  The bridge here has survived the years but others to the south have long since disappeared, taking with them the pilgrims whose commerce helped to build several uncharacteristically large churches along the way. 

If you are up for a detour, or can convince any of the hostel owners in the area to give you a ride, those of Santoyo (Iglesia de San Juan, with beautiful organ) and Támara de Campos (Iglesia de San Hipolito) are among the worthy.  To get there, follow the P-432 west from Boadilla, and turn Left onto the P-431 (which comes south from Frómista).  The trip there is about 12km (visiting both locations), and 7km straight back to Frómista.  If you ask the hospitalero at the Albergue "El Camino" in Boadilla, he will point the way.
