St Mary's College in Bangor was founded in 1893 as a women's teacher training college, the main buildings here were built in 1905. The college merged with the University of Bangor in 1977 and the college, now called St Mary's Site, was mostly used for accommodation until it was closed in 2008.

Book storage in what was the dining hall:
And a tower:
That's it, really - the rest is accommodation, not interesting :)
There's a bit more in my Flickr set...
