Origin and history

Lasson Castle, located in Calvados in Normandy, is an early example of Renaissance architecture in France. Built between 1515 and 1525 on the foundations of a 14th century mansion, it preserves an original Gothic cellar. This castle is emblematic of the first Norman Renaissance, with stylistic influences similar to those of the Church of St Peter of Caen, work by architect Hector Sohier. Its facades, richly decorated with motifs such as roses (the emblem of Thesards) and chimeral animals, contain an enigmatic inscription linked to the alchemy: "SPERO LACO BI ASSES PERLEN", often interpreted as an allusion to the Great Work.

The castle was commissioned at the beginning of the 16th century by the Thesard family, of the bourgeois of Caen, who made it a symbol of their social ascent. In 1628 he went through marriage to the family of Crosmare, which made major changes: Louis de Crosmare added a narrow building to the east end, and in the 17th and 18th centuries saw the integration of the communes and the redesign of the East Towers. After decades of neglect, the castle was bought in 1979 by the Vermès family, and then in 2024 by Guillaume and Anthony Voidie-Broult, who undertook its restoration, including lost French gardens.

Ranked as a Historic Monument since 1917 for its main body (except for an addiction), the castle saw its commons registered in 1975. Its architecture combines a raised house on the left and a house on the right, with a floor and a dotted roof. The exterior decoration, marked by horizontal sticks and heraldic elements, reflects the influence of Hector Sohier. Despite internal transformations at the end of the 19th century, the castle remains a rare testimony of the transition between late Gothic and Renaissance in Normandy.

The site is also known for its mysterious inscription, "SPERO LACO BI ASSES PERLEN", whose interpretations vary. Some see it as an alchemical motto summarising the process of transformation of matter ("L'espoir est dans la dissolution"), while others offer a more symbolic reading ("water and trial is born of true wealth"). This puzzle adds an intellectual dimension to a monument already remarkable by its history and architecture.

Historical sources, such as the works of Arcisse de Caumont or the proceedings of the Colloquium of Cerisy-la-Salle (2003), underline its importance in the Norman heritage. The Château de Lasson is thus part of a network of Renaissance castles in the region, alongside Fontaine-Henry or Lion-sur-Mer, while preserving unique features, such as its medieval cellar and carved decorations. Its present restoration aims to preserve this heritage for future generations.
