The Palais du Marquis d’Assche served as the 1903 birthplace of Prince Charles, Count of Flanders, a member of the Belgian royal family who transitioned from state governance to professional painting. His life spanned major shifts in European history, moving from the turbulence of two world wars to an eventual retirement dedicated entirely to artistic production in the city of Ostend.
Military Education and Early Life
During the First World War, Charles was relocated to the United Kingdom, where his formal education progressed through the Wixenford School in Wokingham and later the Royal Naval College at Osborne and Dartmouth. By 1926, he attained the rank of honorary sub-lieutenant in the British Royal Navy. Following his return to Belgium, he continued his military training at the Royal Military School of Brussels.
