The centre of the square is not a bad place, the same as the arches of Raxoi Palace, to stand facing the Cathedral if you have a wide-angle lens. But if you want a “full-body” photo using a normal lens, the secret lies in going down to the stairs in Rúa de Raxoi, from where you can see the entire façade with the towers. Ideal for group portraits.
And, with a beautiful frame, from the arcades of the Rajoy Palace.
