I am at Santiago now, working at the Pilgrim Office through mid-August. The Cathedral is open. The main altar is in full use, including the Botafumeiro, as per standard policy.
The scaffolding is GONE from the front facade, the West side. There is some work being finished on the front portico and stairs that does not require scaffolding.
This main entry cannot be used yet as the artists are finishing the restoration and authentic painting of the faces on the medieval statues at the Cathedral entry and the Portico of Glory. Until the artisans are done, the main entry cannot be used. But I presume they are trying to get it done as fast as possible. The few statues I CAN see over the plastic fence are AMAZING.
There are some remaining renovations being done on the canopy over the crypt containing the relics of Santiago. There is some residual scaffolding and safety netting. But this does not affect using the main altar.
The main cupola, over the main altar has a safety net, as work on the dome is being finished. But this, also, does not affect using the main altar or the Botafumeiro.
I do not know the exact schedule for finishing the remaining work. I DO know they are trying to wrap it up in time for this year’s Feast if Santiago on 25 July. That is some 8 or 9 days away.
We shall see...
The Cathedral looks magnificent having been thoroughly cleaned, all the stonework regrouted / repointed and all the statuary and gargoyles restored.
Hope this helps.
