Monteriggioni artifacts

There are five artifacts to be found in Monteriggioni during Assassins Creed Brotherhood. The achievement Dust to Dust requires that you find at least one of these.

Marias Feather Chest
Upon exiting the sanctuary turn behind you and run up the wall towards the round window. Take the lift and go to the top of the roof. The feather chest is to the left (it is golden when spotted with eagle vision).

Ezio's Belt
Stick near the right wall and head along roofs towards the very front. The artifact will be on a lower level roof on a fenced balcony (it is golden when spotted with eagle vision).
