Although Spain does not collect official statistics on religious affiliation, the growth of evangelical communities is evident in the steady rise in places of worship across the country.
This trend is reflected in data from the Observatory of Religious Pluralism, an initiative of the Pluralism and Coexistence Foundation, which has tracked and updated the number of worship sites for religious minorities for nearly twenty years.
Evangelical Christianity remains the most established minority religion in Spain, with more than 4,700 places of worship—4,763 in total—recorded in 2025.
Catalonia tops the list by region with 1,010 evangelical worship sites, followed by Madrid with 855, Andalusia with 744, and the Valencian Community with 510. According to the Observatory, places of worship belonging to religious minorities continue to grow nationwide. Although Catholic churches still dominate with 22,922 sites, evangelical congregations are nearing the 5,000 mark.
The Pluralism and Coexistence Foundation has also recently released the Barometer on Religion and Beliefs in Spain (BREC 2025), a study highlighting significant shifts in the country’s religious landscape.
According to the report, 42% of Spaniards do not identify with any religion, including those who describe themselves as indifferent (17%), agnostic (14%), or atheist (11%). Among respondents who do consider themselves religious, Catholicism continues to predominate at 46%, while 8% identify with other religious traditions.
