Langgar Merdeka is a donated building from H. Mas Hadi, which originally belonged to a Chinese owner. The construction of the prayer house began in 1942 and was completed on February 26, 1946. During the Dutch Military Aggression in 1949, it was used as a base by Indonesian fighters and was temporarily renamed Langgar Al Ikhlas. However, after the Dutch aggression ended, it was renamed “Langgar Merdeka.”
