Yverdon’s Hôtel de Ville was designed by two late 18th century artists, Abraham Burnand and Béat de Hennezel. According to Abraham Burnand, their aim was to “give important buildings the true beauty and grandeur which should distinguish public edifices.” He added, “A public building destined to last through the centuries should conform to all rules quite precisely, exemplifying the noble simplicity that is appreciated by true connoisseurs throughout the centuries.”
