Sigh.  You're removing information from OSM again. If you look at the history of https://www.openstreetmap.org/node/3153973098/history you can see that something allegedly was a castle.  You've changed that to just "fortification", of which a (former) castle is just one kind. There's at least one documented data consumer (me) that distinguishes between different historic and archaeological fortifications.
You may, of course, have rwsearched exactly what this site is/was - if so, I'd be delighted to know what you've found....
