The Church of the Annunciation of the Blessed Virgin Mary, known in Spanish as Iglesia de la Anunciación de la Madre de Dios, is a temple of the Spanish-Portuguese diocese located in Barcelona at Carrer de la Mare de Déu dels Reis, 12. The church is led by Archimandrite Seraphim (Pavlov).

Previously, this territory belonged to a Camillian monastery. In 1910, the Camillians built a church here in honor of Saint George, which became the first standalone church in Barcelona dedicated to this saint.

On July 5, 1956, an independent parish was established at the church. However, with the increase in parishioners, the need arose for the construction of a new church with additional buildings. The church, laid in 1965, was consecrated on December 16, 1973. After that, services at the Church of Saint George were held only occasionally, and the building gradually fell into disrepair.

In the summer of 2011, an agreement was reached to lease the dilapidated church to the Russian Orthodox Church.
