Hi - it sounds like an exciting project. There are two things to focus on with this work - firstly the content - what you put into the work. This is the most important aspect and the information you present needs to be accurate, interesting and attention grabbing. The second aspect is the presentation itself - the fonts, the colours and the images that you use.
As a good historian, focus on the content first. You've got three key questions. I would suggest trying to show a series of images that show the cathedral as it was in the middle ages and then how it has changed up until now. If you do some research online you should be able to find quite a few images. Make sure you include the source for each image. You could then use these images to explain how the cathedral has or hasn't changed over the years. For the 'main features' you need to look at the design and layout of the cathedral. Are any parts of the cathedral set out in a particular pattern or arranged in a certain way? Many medieval cathedrals had a very specific layout and it would be good to look into the importance of this. Finally, you can like your 'evidence of changes' back to the images that I've suggested - you can show how the cathedral has physically changed over time and then try to focus on your evidence to prove your points.
Good luck. Once you've got all your information together you can then present it in a professional way. Try not to go over the top with the presentation. Find a smart and professional font, use animation carefully (too much will make your work look daft) and don't overload your slides with too much text.
