At the time of the Dominican nuns, the convent was supplied with water by a well dug in the cloister garden. Its location was rediscovered during the renovation work undertaken between 2013 and 2015 by the ‘Monuments Historiques’ organisation. The board of the Unterlinden Museum has decided to move in the cloister the well of the former tailors’ guild of Colmar which, before the works, was placed in front of the former entrance of the museum. The Rouffach yellow sandstone well, built around 1610 and transferred to the museum in 1875, had to be completely dismantled before being transported and reassembled in the cloister garden.
