Castle Saburac ?
This is a fictional location from a tv series called Catweazle. He was an 11 century wizard who was being chased by the Normans, jumped into a lake and surfaced in 1960's rural England. He set up home in an old army water tank which he called Castle Saburac. (When spelled backwards incidentally this comes out as carubaS).
Catweazle had a familiar who was a toad called touchwood and he befriended a local lad called Carrot. Carrot astounded Catweazle with his command of such magics as electrickery and the telling bone.
I got the boxed set on DVD about the time I picked the avatar.
