Wars of Religion after the Massacre of Vassy, arrests for heresy began in 1562. While the Count of Montgomery was recovering Béarn from Catherine's allies in 1569, he went on to demand large ransoms from her other towns, including Bagnères. (It is unrecorded whether the people of Bagnères paid him, but he is recorded leaving the town unmolested and leaving for Gers.) The governor of Bagnères Antoine Beaudéan was killed by the Protestant warlord Lizier in an ambush near Pouzac in 1574. By the end of the Wars of Religion, the town was ruined. Plague also returned in 1588. The outbreak ended following a religious procession prompted by the "Lighting of the Liloye", a Marian apparition at the Chapel of Notre-Dame-de-Médous. The ascension of Jeanne's son Henry as king of France in 1589 united his titles—including count of Bigorre—with the French monarchy. Early Modern era The plague struck Bagnères again in 1628, 1653, and 1654. Public health measures were taken, with most patients isolated in the Salut Valley. The disease did not reappear after December 1654. On 21 June 1660, strong earthquakes hit the town, continuing for three weeks. Only seven people were killed, but 150 houses were damaged and the springs initially dried up. This was only temporary, however, and the water flowed again sometime later. Reconstruction was carried out with dimension stones from the Salut Quarry. This stone has the distinction of becoming like marble once polished, a feature that characterized the architecture of the town afterwards. Hydrotherapy was gaining importance. There were 25 private businesses by 1787. In 1775, a convent building was transformed into a gambling establishment called the Vaux-Hall where there was also dining and dancing. This is the first casino in Bagnères. French Revolution During the French Revolution, "moderate suspects" took refuge in the city from 1789 to 1793, ready to flee to Spain if the situation worsened. The departmental authorities were wary of the Bagnèrese, to whom they ascribed little civic or revolutionary spirit. In late 1793, before the hospitals in the southwest became saturated, the wounded were evacuated to spas. At Bagnères, the Saint Barthelemy Hospice, the Uzer and Lanzac houses, and the Hospice of the Médous Capuchins were used as military hospitals. Industrialization In the 19th century, the hydrotherapy offered by Bagnères's spas was reckoned particularly effective for digestive complaints but the private spas were growing more decrepit. In response, the
