King Gontran and his squire fell asleep near a stream. The squire saw in his dream a little lizard came out from the king's mouth. The animal started to run to the hillside and came back with golden dust on his skin!
The squire awoke the king and they started to seek some gold... they finally found a treasure! So the place naturally became "treasure hill", Montrésor! But the legend was wrong, because some medieval archives said the fief belonged to the treasurer of the cathedral of Tours.
The first lord was mentioned in 887, when he rode with other knights to bring back saint Martin's body in Tours city. The canons wanted to thank him and gave him a plot of land overlooking the river Indre. The lord raised a former keep...
In the 11th century, Foulques Nerra became allied with lords of Montrésor: Roger, nicknamed "Little Devil", was rewarded by Foulques, who allowed him to raise a bigger castle. In the end of the 16th century, lands fell to family de Breuil. Jean III, Jean IV and Jean V de Breuil embellished the castle.
This one fell to Imbert de Bastarnay in 1493: this one transformed the fortress into a nice Gothic dwelling, next to the keep. Then, the castle fell to several famous families in the 17th century, as for instance the Guise and the Joyeuse. In 1849, count Xavier Branicki, city mayor between 1860 and 1870, bought Montrésor. His descendants owned it.
