If there’s one image that seems – to me at any rate – to encapsulate the whole of the Grenoble Archaeological Museum, it’s the sight of these two doorways, one inside the other, with just a little of the richly painted decoration peeking through. The earlier arched doorway was built in the late 12th to early 13th century and features painted scenes on the intrados. At the centre, there’s a depiction of the hand of god – the ‘Dexter Dei’ – with St Peter and his key on the left. St Michael appears to the right, though only his name and wing-tip are currently visible behind the remaining stonework. That stonework and later door were inserted in the 15th century. When I first came here in 2000, only a little of St Michael was visible. It is clear that part of the restoration of the site included the decision to reveal more of this amazing paintwork.
