The cobblestoned threshing floor dates back to the 16^th century. Its exposure to the wind made it ideal for threshing and drying the wheat. The splendid view from the threshing floor lets you admire the whole of Vieil-Oppède. To the north-west of the plateau, you will find the remains of a small chapel – the Chapel of Sainte-Cécile - that is of Roman origin.
