To better the conditions of the pilgrims that began to use his new causeway, he replaced the wooden bridge that he had built with Gregory with one made of stone, and constructed on the site of an old fort, a building that served as a hospice for travelers.

Alfonso VI of Castile annexed La Rioja in 1076 and seeing that Dominic's efforts contributed to the Castilianization of the region, decided to support him and his projects.
