Ist das auf Armenisch geschrieben?

The letters are Armenian but the words dont make sense or its some old Armenian that I dont understand

Definitely Armenian, but very hard to read. Some of the letters look really weird and the words make no sense. It could be another language using Armenian script

I’ve seen this before:

Յիշատակ է Կեսարիեայ Սուրբ Աստուածածնայ եկեղեցուն, ՌՄԾԴ (1805)ին:

Might not be the same plate, I can’t tell what the letters are for the year. You say World War 1; 1805 ain’t that.

Edit: Not sure on the year, and looking at it again I think that last word is „եկեղեղեցոյնէ“ not „եկեղեցուն“.

This looks like church’s plate because it says “saint (can’t read, weird letters) church” or at least it is what I see

Seeing your nickname I really hoped your great grandfather would have died

A token of remember from the resurrected church from the central village. 1805.

It’s in ancient Armenian, which lends support for the date.

You want to understand its history, and your own, take it to the oldest Armenian church in your village and ask them.

This isn’t a simple souvenir you’d buy at bazar, it is possible one of your Armenian ancestors may have helped resurrect the church.
