Louis-Philippe, Crown Prince of Belgium (24 July 1833 - 16 May 1834) was the eldest child and heir-apparent of Leopold I of Belgium and his second wife, Princess Louise d'Orléans.
Louis-Philippe became crown prince at birth in Laeken. The baby was baptised at the St. Michael and Gudula Cathedral in Brussels by Engelbert Sterckx, the Archbishopric of Mechelen-Brussels.
Louis-Philippe died in Laeken before his first birthday of an inflammation of the mucous membranes. He was buried with the remains of his parents in the royal crypt of the Church of Our Lady of Laeken.
Unlike subsequent heirs apparent to the Belgian throne, Louis-Philippe was not Duke of Brabant; this title was not created for the heir-apparent to the throne until 1840. He was followed as crown prince upon the birth of his younger brother, Leopold, who would later succeed their father as Leopold II, King of the Belgians.
A little south of the royal castle in Castle, you can find the neo-gothic Church of Our Lady, initially built as a mausoleum for queen Louise-Marie, wife of Leopold I, whose children included Leopold II of Belgium and Empress Carlota of Mexico. The architect was Joseph Poelaert, designer of the famed Brussels Palace of Justice. The church contains the royal crypt, where the members of the Belgian Royal Family are buried.
