Montseny began to be populated during the 14th century and for this reason we think that the El Buxaus farmhouse was built during this period.
During the epidemic of the Black Death the farmhouse was probably abandoned, as life on the plain was less difficult than in the middle of the forest, it happened in all the mountain farmhouses.
Due to the abandonment during the later centuries the part of the main entrance and the kitchen collapsed, is a fact that can still be seen today on the facade of the house. The reconstruction was done by a farmer from Occitania during the second half of the eighteenth century, this farmer gives his name to the house, his surname was Buxaus.
