 The Palace of St. Michael and St. George, built in 1815 by Sir Thomas Maitland (1759–1824; Lord High Commissioner of the Ionian Islands) is a large structure of white Maltese stone.Near Gasturi stands the Pompeian style Achilleion, the palace built for the Empress Elizabeth of Austria, and purchased in 1907 by the German emperor, William II.Of the thirty-seven Greek churches the most important are the cathedral, dedicated to Our Lady of the Cave; St. Spiridon's, with the tomb of the patron saint of the island; and the suburban church of St Jason and St Sosipater, reputedly the oldest in the island.
