Very irreverent of me, I know.
I love a country that will make a church in a tiny building like this, rather than not have one at all.
It was unlocked when I visited, the door sticks a bit so make sure you close it properly if you do peep inside at all the icons.
It's said if you build a church you have a special place in heaven, nobody specified dimensions 
I hope when the new one is finished it's not demolished.
Unfortunately the builders are not very clean and tidy people, but the cache is at eye level, so no need to worry about the junk, of course it is NOT in the church.
Cache is one of those 600ml plastic jars with a blue lid. Plenty of room for TB's and swaps.
Congratulations to the nocturnal pseacraft
