Thanks for that, some of the pillars are actually leaning but the lens I used is a Canon 10-18 (roughly) so there is bound to be some distortion. I will give it a go later, thanks again.

If I may make a suggestion, in Lightroom 4.4 (I think this is the version you have), go to the Develop > Lens correction > Manual and move the Vertical slider to +40 and check the constrain crop.
I think you will be pleasantly surprised with the outcome.
