Found these photos as the interiors of the Alexandria Palace in Neskouchnoe.
That's not Neskutchnoe palace. It's the Neues Palais in Darmstadt.
Look at the bow window room, at the gallery...
Besides the bow window room's photos are very interesting as they were taken in two different times.
the first apparently in Princess Alice's times (it resembles Osborne House so much!)
the second when the corner window was walled up.
