Tour de Nesle
The Tour de Nesle or Nesle's Tower was one of the four large guard towers on the old city wall of Paris, constructed at the beginning of the 13th century by Philip II of France and demolished in 1665. The tower was situated on the left (south) bank of the Seine facing the old castle of the Louvre on the opposite bank. Originally known as the "Tour Hamelin", it was a cylindrical structure of approximately 10 metres in diameter. The height was around 25 metres, with a stair turret reaching higher still. Later, the tower was  incorporated into the Hôtel de Nesle, a medieval mansion. On the right bank of the Seine river, was a similar tall tower : the "Tour du Coin" (=Corner tower). The towers protected the upstream approach into the city towards the Île de la Cité. In 1308, Philip IV bought the tower from Amaury de Nesle. In 1314, there occurred a scandal known as the "Tour de Nesle affair" (""), during which the daughters-in-law of Philip IV, were accused of adultery. Much of the adultery was said to have occurred in the Tour de Nesle. The scandal led to torture , executions and imprisonments for the princesses' lovers and the imprisonment of the princesses, with lasting consequences for the final years of the House of Capet. In 1319, Philip V donated the building to his Queen Jeanne de Bourgogne (the one accused who was found innocent) and she, in her will, left it for the College of Burgundy, which she founded for the University of Paris. Demolished in 1665, mansion and tower became the place of the Collège des Quatre-Nations (later occupied by the Institut de France) with the Bibliothèque Mazarine. In popular culture. In the 19th century, Alexandre Dumas  wrote the celebrated romance "La Tour de Nesle" (1832), in which he portrayed the place as a theatre of orgy and the place of murder of a Queen of France at the beginning of the 14th century, (likely Margaret of Burgundy). His story is based on the fifteenth century legend based on events alleged to have taken place in 1314. The story was also the basis of a 1955 film known in English as "Tower of Lust" (French: "La Tour de Nesle"). "Le Roi de fer" (1955), the first novel of Maurice Druon's seven-volume series "Les Rois maudits  (The Accursed Kings"), describes the affair and the subsequent executions in lurid and imaginative detail.
