Posted on March 22, 2018April 1, 2018 by WillemThursday/ Mazatlán churches I walked to two beautiful churches here in the city so that I could take a closer look. The Cathedral Basilica of the Immaculate Conception is the main religious building in Mazatlan and is located in the historical center. The original building was completed in 1899. This is the inside of the church, looking forward towards the altar. Here is the Parroquia Cristo Rey (Parish of Christ the King). Its style is unusual and I could not immediately find more information about it online. The main entrance to Parroquia Cristo Rey (Parish of Christ the King). Those pesky telephone cables interfere with my picture!
