My tip“Friday prayer is usually between 13:30 and 14:30 (it may be delayed to 15:00 in summer); check with the mosque before going. The sermon is around 14:30 and the place fills up, so arrive half an hour early. It has a separate women's prayer room.”
Spain’s largest mosque, opened in 1992 with Saudi funding, with a large prayer hall, a school, a library and a halal restaurant.
