This town house was built for Jacques Coeur, who lived here in the 15C. In the 17C it became the headquarters of the magistrates responsible for administrating the royal estates in Languedoc. They had the grand triple-flight staircase built and the courtyard façade with superimposed colonnades. The name Lunaret pays homage to Henri de Lunaret, who donated it to the Montpelier Archaeological Society, founded in 1833.
