Remains of an ancient synagogue were discovered during the hotel's construction last year and the mikvah was preserved as part of the building plan.
A Spanish hotel built on the remains of a 15th century synagogue opened a new synagogue on its seventh floor.
The opening last week at the four-star Parador de Lorca hotel in Lorca, a city in the southeastern region of Murcia, was the result of negotiations between management and the Sefarad Beitenu Jewish association, which will run the shul, according to a report in the Murcia Economia newspaper.
The president of Sefarad Beitenu, Aharon Franco, signed a cooperation contract with the Paradores hotel network on Dec. 4, the report said.
The synagogue was unearthed during the construction of the new hotel, which was opened last year.
The seventh floor also houses a small Jewish cultural center offering an overview of Jewish history in Spain and a description of the synagogue and other findings recovered in the ruins.
Several heritage preservation groups opposed the hotel's construction because it would mean the loss of archaeological finds. The management pledged to incorporate the findings, including a 15th-century mikvah, or ritual bath, into the building's architecture.
Shlomo Amar, a former Sephardic chief rabbi of Israel, visited the hotel and the ruins earlier this year and requested that it be made into a place of pilgrimage for Jews, according to the Spanish daily La Opinion de Murcia.
