84 Infantry Division (USA) HQ at Blier

I am wondering about something. My father was wounded Jan 11 1945 near the village of Samree BE. He was removed from the battle field strapped to the front of a jeep. later he was placed on a train that was heading to Calais... at some point his brain began to swell and the train was stopped and he was taken off by German POS. He was taken into a place he described as a Castle with elaborately painted ceilings. But it was not a hospital..yet they did have some medical personnel who cared for him until he was healthy enough to continue on. He had no idea where this was... but seemed to be the only patient.... at one point he wondered if this was Versailles...but I find nothing to support this.. but it occurred to me that he might have been at a headquarters of some sort... But this website noted that the 84th had headquarters on Jan 11 1945 near Blier... could that have been in the Chateau de Blier? If so.. are their ceilings elaborately painted and could there have been a rail line not far away? The other option was Harze Castle..which appears to have housed military heaquarters during the war and might have housed the 84th... around Jan 27th? I am wondering if there is a possibility that he could have been treated in one of these locations...prior to getting treated for his head injury in Wales. I have been trying to piece together his movements. He was in co E of the 335th Reg of the 84th. Thanks for any thoughts
