Santo Domingo de la Calzada - Cathedral

The town was founded by the hermit Domingo de la Calzada (aka "Dominic of the Causeway"), who supported the pilgrims on the way to Santiago de Compostela. Domingo not only built a hospital for the pilgrims, but as well a paved causeway and a bridge.

He was such a successful architect, that he is still patron saint of the Spanish civil engineers. The first church, erected by him, got consecrated in 1106. The Romanesque apse and the ambulatory of that church have survived the times. Under the roofs of the apse are some great corbels and capitals.

I am not sure, but this scene may illustrate

Genesis 19:1

"The two angels arrived at Sodom in the evening, and Lot was sitting in the gateway of the city. When he saw them, he got up to meet them and bowed down with his face to the ground."
