I had forgotten how grand the Savoy Palace at Racconigi is, much of it nineteenth-century on an earlier core, with a picture gallery of the Savoyards established in the 1920s (the Kings of Savoy lived in it till the 1940s when they were exiled to Portugal) and grand plasterwork decoration in the Sala d’Ercole and Sala di Diana by Gianni Battista Borra, after he had gone on the expedition with Robert Wood to Asia Minor.   But no photography was allowed and it was too far to walk across the park to the nineteenth-century brick Orangery (last time we were allowed to drive).   We retreated for lunch to La Posta in Cavour, which has a pair of weighing scales outside so you can weigh yourself before lunch and after.
