The commune of Pont de la Roque was the subject of a first Allied bombing on April 23, 1944. The bombers targeted the stone bridge built over the coastal river of Siena. Nearly 20 air raids were launched to destroy this bridge and it was not until mid-June that three of the eleven arches were destroyed by bombs.

Very early in his activity, he participated in the flourishing economic life of the region. Coastal and offshore fishing (armament for Newfoundland), navigation school, commercial exchanges thanks to the Montmartin fair, protection provided by the castle: it seems to have all the assets. In 1871, the commercial movement of the port again resulted in the entry of 960 boats representing 21,000 tonnes of goods, mainly the transport of limestone and slaked lime to Brittany and the importation of coal for the lime kilns. But its activity will drop suddenly at the end of the 19th century, following the increase in the tonnage of ships incompatible with the low water levels: the appearance of the iron and steam navy will be fatal to it. At the beginning of the 20th century, it suffered several storms. Currently, its activity is solely focused on pleasure boating (90 anchorages). NB: 1 foot = 324mm; 1 barrel = 2.83 m3 (measure used to measure boats).
