That is a harder question than it sounds. The answer might actually be "there are no such examples", but I'm not confident enough to jump to that with any certainty by any means. Near and inside black holes, there can certainly be significant warping of space, but it's unlikely to be near exclusive warping of space.
The only plausible example I can think of that isn't purely theoretical / speculative would be gravitational waves.
