Turku, Finland

Imam Baqir Islamic Center

Confirmed by Shia news coverage (ABNA24) of Eid al-Fitr prayers held here in 2023. Contact details are for Turun Islam Keskus ry ("Turku Islamic Center"), the only association in Turku's community registry explicitly tagged as representing the Shia tradition — likely the same organization under its common English name, though this hasn't been independently confirmed.
