The town's name derives from 'Mire' to gaze at the hill 'Mont'.

The old royal Bastide town, Miramont de Lauzun, was founded in 1278, by Edouard I on the duke of Lauzun's land, on the site of one of the Templier's refuge and surveillance post. Its arches, many of which are missing, are supported by very old pillars on stone crepidomas.
In 1453, at the end of the Hundred-year war, the king, Charles VIII, granted Miramont the statute of Bastide town.

Isidore Soussial, returning from a stay to Tunisia, in 1848, he created the "Kroumir", a slipper in thin sheepskin worn as clog in the countryside. In approximately 1880, his son Joseph manufactured the item. This was a family business and a cottage industry grew, and the number of clog makers or cobblers soared with more than 20 that made the slippers. At the beginning of the 20 century the modern shoes making factories were established for which Miramont is renowned.
Anyone visiting Miramont can take a tour of the Ruelles (alleyways), which have are full of historical interest. Accompanying literature can be obtained from the Office de Tourisme.
