I was up there last week in search of my great Grandfathers resting place.
The MidWales hospital was an assylum which treated prisoner of war during WWII and were buried in the grounds, the hospital is no longer used and rundown it was privately bought and the entrance is now made up of offices allthough you can still access the main parts of the hospital by driving through the main entrance.
The Bronllys Hospital is the Sanitorium which as allready stated was for T.B. treatments, This is what my GG/Father (who was a service man (merchant navy)died of in 1941, the burials were in the nearby church, but during this period the grave were not maked (no headstone) records show just rows and numbers, so it can be worked out that the person that was buried would be within this 10 foot of space (soo to speak).
I will be visiting again if I can find his co-ordinates of his burial.
So anyone searching for a relative who was a serviceman can easily get the hospitals mixed up beacause service men were also at mid-wales but they were POW's
