The lords of Beaugency attained considerable importance in the 11th, 12th and 13th centuries; at the end of the 13th century they sold the fiefdom to the Crown. Afterward it passed to the house of Orléans, then to those of Dunois and Longueville, and ultimately again to that of Orléans. The city of Beaugency has been the site of numerous military conflicts. It was occupied on four separate occasions by the English. On June 16–17, 1429, it was the site of the famous Battle of Beaugency, when it was freed by Joan of Arc. Beaugency also played an important strategic role in the Hundred Years´ War.
The 36m high square tower of Château of Beaugency was built in the 12th century. In the 1530 cardinal Le Longueville ordered bo enlarge the keep as a larger castle. It was burned by the Protestants in 1567 and suffered extensive damage to the walls, the castle, and the church.
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
