Every year the fourth graders from the International School of Phnom Penh come to visit the Catholic church in the Boeung Tum Pun area of the city as part of their study of major religions. They hear what Christianity is about and get a chance to see the church and the sacristy (the room where all the vestments and supplies are kept), and then to examine up close the statues, stained glass windows, etc., in the body of the church. And then they ask questions. Fourth graders have a lot of questions!
