What's the Name of That Book??? discussion

I feel like this was a trilogy and I read these books in the late 90s / early 2000s.

All I can remember is that the protagonist (I think it was a girl) was in this magic 'school' in a stone building almost cut from the rock of a stormy island.

I might be wrong, but there was possibly a shipwreck on the beach which was down steep, slippery stone steps from the school. I think there was a young boy character as well.

Any help is greatly appreciated!

What country were you in when you read this book? Language?
Anything about the cover?
Time period story takes place?

What sort of magical elements were in the story: witches, spells, dragons, etc?

Possibly the Echorium books?
