Easy way of checking what buildings you've renovated?

Hi there,

At the moment I am getting stuck into renovating buildings in Rome. I was wondering if there is an easy way of doing this instead of actually walking up to them and seeing if they are open or not.

So far I have only destroyed Borgia towers if I have got enough gold to renocate everything in that area but there must be an easier way.

Can you check by just looking on the map or any other way?

Cheers!

After checking the map, only the Landmarks say they have been purchased if you have already bought them but the shops do not. They appear faded so thank you very much for your answers.
