Locations of foreign worship are typically of concern. You're not supposed to enter a church for this very reason.
My question relates to the idea that one finds out their home was previously used for foreign worship. Say they discovered that they live in a home that was previously used by a pagan of some sort.
Assuming that moving wasn't an option, what would be the process of purifying the space as a Jewish home? Would simply living a Jewish life and restructuring the location for Jewish worship be enough?
Clarification:
In the example I'm giving, the house itself was not built specifically for idol worship or used as a formal location of idol worship. That being said, in the same way a Christian might light candles at a shrine in their home, the house would have had foreign worship occur within it. That was the context of the example I was giving.
