I am a muslim, regretfully, a bad example. A shame to my own folks.
Anyway, there is no mosque in santiago but I think there is a mosque being built in santo domingo. I am sure many college muslim students have a house converted into a mosque in santo domingo. The last time I stepped into a mosque was in Dubai but unfortunately not for praying, I needed to use a clean washroom.

P.S. you can send me a private message if you need to contact me. I am originally from pakistan but live in santiago.
