Sacred Heart Church is one of the well known churches in Manville, NJ. It was built back in 1914 after the Johns Manville asbestos factory brought in Polish immigrants. Polish families were looking for a place of worship and were forced to use other locations before Sacred Heart was built. Once it was established the church brought in people from all over. Still running today, the church is well known for its summer Polish Festival where people from all over the state come for their famous ethnic Polish food.
