In a word, ‘Churches’ encompasses this section. I have managed to see inside a few but my luck has not been especially great concerning this particular type of explore.
Many churches have been closed for over a year now, as they are considered places of ‘mass gatherings’. I would have expected more to have become abandoned but in most cases, they are sealed very well.
The ones I have managed to infiltrate have mostly been gutted inside or desecrated. You can be sure to see the word ‘satan’ if you look hard enough.
