On the slopes of Oka Mountain (150m/492ft) stand a series of simple whitewashed stone sculptures representing the Stations of the Cross and Calvary. The four oratories and three chapels were built between 1740 and 1744 by Hamon Le Guen, a Sulpician from Brittany, in an effort to evangelize the indigenous population. The mountainside provides a fine view of the park and of Lake Deux Montagnes.
