San Salvador de Nogal de las Huertas

The architecture is significant as the oldest surviving example of the Palentine style [es], the romanesque idiom of the province of Palencia.

It was founded in 1063 by the Countess Elvira Sánchez, and originally constructed with a central nave and a square apse.

In the mid-twelfth century, Rodrigo, youngest son of Count Pedro González de Lara and his wife Eva, became its prior, an unprecedented move for a male member of an aristocratic family in Castile.

[1] In the thirteenth century two lateral naves (aisles) with the pointed arches typical of the Gothic style were added.

In June 1931 its ruins were declared a monumento histórico–artístico, nowadays called a conjunto histórico.
