Looking for old horror film

I can't recall a lot about the film, actually. I recall it being a B&W
film, probably from the 50's or early 60's. It played a couple of times
on Sammy Terry'sold show on channel 4 out of Indianapolis when I was a
kid. Anyway, it centered around an island graveyard. If I remember right
it was set somewhere in Europe. All I really recall is that the main
characters got to the island by boat and spent the night there. I recall
them being locked in a crypt at some point. I know that's all kind of
vague and generic, but that's all I really recall, other than that I
found it scary at the time.

Anyone got any ideas?
