Cologne Charterhouse (Kölner Kartause) was a Carthusian monastery established in 1334. The monastery developed into the largest charterhouse in Germany until it was forcibly dissolved in 1794 by the invading French Revolutionary troops. The building complex was then neglected until World War II, when it was mostly destroyed. The present building complex is very largely a post-war reconstruction. Since 1928 the Carthusian church, dedicated to Saint Barbara, has belonged to the Protestant congregation of Cologne.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
