The Hôtel Saint-Pol (French pronunciation: [otɛl sɛ̃ pɔl]) was a royal residence begun in 1360 by Charles V of France on the ruins of a building constructed by Louis IX.
It fell into disuse and ruin after the death of Isabeau de Bavière in 1435 and was demolished after Francis I of France sold it in parts at auction in 1543.
From then until 1364, Charles continued to improve and develop it by acquiring additional property, including the newer Hôtel d'Étampes in 1361, and ordering the construction of new buildings.
He valued the residence for its calm and its cleaner environment, which he claimed had helped him avoid illnesses, and more importantly recover good health.
Charles VIII, Louis XII, and Francis I lived in the Loire Valley or at the Château de Fontainebleau, and the Hôtel Saint-Pol fell into ruin.
