The historic features of the house include murals dating back as far as the 13th century and a 15th century ceiling with original hidden paintings. The house has two fireplaces of note, including one in the Grand Salle (Louis XV - 18th Century) and another, possibly of earlier construction, in what is now the kitchen. Originally owned by the Abbey, some form of accommodation may have stood on this site since as early as the 8th century. A pillar at the front of the house features stone carvings of the faces of the 14th century owner and his wife, together with a coat of arms carved in the ancient wooden beam above. The large door at the main entrance to the house dates from the 15th Century and is similar to others that can be seen in historic buildings around the region.

While the village of Lagrasse is classified
as a "Monument Historique" the external
facade of the Maison Maynard (everything
below the balcony) has an additional
classification, thus protecting the carved
pillar and wooden beam, which are featured
in many guide books of the region.

The recently completed renovations revealed
an ancient Gothic style stone arch in the
kitchen and additional murals in the Grand
Salle. A team of French Government
authorized professional restorers was
engaged during 2003 and 2004 to clean, restore and protect the murals. This work has now been completed. Initial work on the ceiling in the Grand Salle included reparation of various damaged areas and replacement of the decorative corbels, six of which had earlier been removed. Future work will involve possible retrieval of some of the many small paintings that exist on wood panels in the ceiling. One, a painting of an angel holding a shield, can clearly be seen on a ceiling   section next to the fireplace.

Local history books and village records state that the house was owned in the 15th century by the family of the Jesuit Saint Jean Francois Régis
(b. Font-Couverte, Narbonne).
