With the Ottoman conquest, the castle lost much of its strategic significance, although it was occupied by the Venetians during the Ottoman–Venetian War of 1463–79, and attacked by the Knights of Malta in 1620. During the period of Venetian rule in the Peloponnese (1687–1715) after the Morean War, it served as the seat of a fiscal district. The reports of the Venetian governors at the time, however, dismiss Chlemoutsi as small in size and barely inhabited. In 1701 the "provveditore generale" Francesco Grimani proposed that it be destroyed, as it was too far from the sea—a vital concern for the maritime-minded Republic—and difficult to defend, and recommended that Glarentza, by then abandoned and ruined, be rebuilt instead. In 1715, the Morea returned to Ottoman control, and by the early 19th century, the fortress had been completely deserted. In 1825, during the Greek War of Independence, the forces of Ibrahim Pasha of Egypt took the castle and dismantled a portion of its walls, so that it could not be used by the Greek rebels.
