Barcelona has 37 religious confessions and 535 places of worship, according to the city council’s 2024 activity report from the Office of Religious Affairs. The figures show a city with a wide mix of beliefs, and a large share of residents who do not identify with any religion.
Catholic Christianity remains the largest faith group, at 39% of residents. Non-believers, atheists and agnostics together account for 47%, including 29% who describe themselves as non-believers or atheists and 18% who say they are agnostic.
Other Christian denominations, including Protestant and Evangelical churches, Jehovah’s Witnesses and Orthodox communities, make up 5% of residents. Muslims account for 4%, while Hindu, Buddhist and Sikh religions together represent 1% of the population.
Across the city, there are 233 Catholic Christian centres, or 43.6% of all worship sites. Evangelical Christian centres are the second largest group, with 182 spaces, equal to 34% of the total. Muslim prayer rooms number 39, or 7.3% of worship centres. Combined, Catholic and Evangelical centres make up 415 places of worship, nearly 80% of the city total.
The distribution is uneven across districts. Eixample has the most centres, with 69, followed by Nou Barris with 66 and Sarrià, Sant Gervasi with 63. Sants-Montjuïc has 61, Sant Martí 59, Horta-Guinardó 55, and Ciutat Vella and Sant Andreu 53 each. Gràcia has 37 centres, while Les Corts has the fewest, with 19.
Evangelical temples now outnumber Catholic churches in four districts, Sants-Montjuïc, Nou Barris, Sant Andreu and Sant Martí. Catholic centres still dominate in Ciutat Vella, Eixample, Les Corts, Sarrià, Sant Gervasi, Gràcia and Horta-Guinardó. The Office of Religious Affairs has also held discussions with representatives from several faiths, including Moriah Ferrús of the Jewish Community of Barcelona, Peio Sánchez of Santa Anna parish, Mohammad Iqbal of the Camí de la Pau Islamic Cultural Centre, and Albert Riba of Atheists of Catalonia and spokesperson for “Jo no t’espero”.
