The Friedrichstein Castle stands as a primary example of the work produced by John von Collas during his career as a late Baroque architect. Born in Sedan in 1678, he transitioned from a French Huguenot upbringing to becoming a significant architectural and engineering force in East Prussia throughout the early 18th century.
Early Life and Exile
Born to Antoine de Collas and Elisabeth née de Vilain, he spent his formative years as a French Huguenot. Following the 1685 Edict of Fontainebleau, his family fled France, seeking refuge in the Netherlands and eventually London by 1688. During his time in England, he resided at the estates of William Russell, 1st Duke of Bedford, and served as a page to Mary Butler, which included carrying the train of Mary II of England at her 1689 coronation.
