The pagoda is located around a small square. Currently it has 3 main objects for praying. One inside hall, pagoda with a bell where you can write a wish and also climb to top floor and third is under construction with a golden statue. Unless you want to pray, the visit will take you roughly 20 minutes. I asked if it is a buddhist place or what religion does this belong to and one vietnamese family from Hanoi told me, that they actually don't know. That's my feeling from most of the newly built pagodas in Vietnam. They all are like prayin fastfood with no spirit or very little religious background.
Notice the church on the other hill. It might we worth visiting.
