Sainte-Marguerite, Paris

The church of Sainte-Marguerite sits tucked away behind a modest iron gate, marked by a plain, severe facade that hides its deep eighteenth century roots. It holds the remains of Louis-Charles, the young son of King Louis the Sixteenth, who died in the nearby Temple prison during the revolution. While some argue his body rests elsewhere, the church became a pilgrimage site for monarchists who left flowers and messages for the lost child, turning this quiet corner of the eleventh arrondissement into a historical puzzle.
