This baroque pavillion with a regular septogonal base is part og the parc of Enghien and belongs to the Enghien's castle.
It is situated at the highest point of a septogonal garden and is surrounded with a pond. Seven paths go from the centre of the pavillion and seeme to dissappear in the horizon. To accentuate this effect seven smaller paths go from between the larger paths and end with seven statues representing the seven planest known at that time.
There is a remarquable sphinx in the pond.
It is said to be in use as a sun calendar.
