 It was first thought that the pillars of the old mosque found within the current mosque are the pillars of the original built in 1380.However, studies from the National Museum of the Philippines have confirmed that the pillars found within the present mosque dates back to the 17th century, making them remnants of a reconstruction of the mosque during the 17th century, and not the 14th century.Nevertheless , the four pillars are regarded as sacred and have high status in Philippine culture as they are at least 400 years old and are the oldest known Islamic artifacts in the entire Philippines.
