Camilla, an avid reader, was also given a private tour of author Victor Hugo’s home, Hauteville House, which she declared a “remarkable treat”.
The property, built on the heights of Saint Peter Port, is where Hugo wrote many of his masterpieces, including much of Les Misérables, Toilers of the Sea, and The Man Who Laughs.
Hugo lived there for 15 years during his exile from France and left the property to the French government, which preserved it as a museum in his honour.
The King and Queen had earlier arrived on the island to the sound of a 21-gun salute, marking the first visit by a reigning monarch since Elizabeth II’s in 2005.
The King presided over a short outdoor sitting of the States of Deliberation, the island’s parliament, featuring a fanfare, two verses of the National Anthem and the Lord’s Prayer delivered in French.
Before they left, a group of schoolchildren from Sark sang Happy Birthday to the Queen in the island’s native language, Sercqaise.
But after a brief rest at home, both King and Queen will be straight back to it on Wednesday, when they take centre stage for the State Opening of Parliament.
