The convent alas is no more. It was the end building of Orwell Terrace, closest to the sea. About 5-6 years ago, possibly more, the foundations became unstable and the whole building fell down. Orwell Terrace still exists, mostly converted into flats, it's only the convent that collapsed.
What photographs in particular did you want? I could probably find one of the convent as it was originally.
I assume that you don't live in the area?
