At this point of passage between Prussia and Belgium in the 19th century, there was a border post where Belgian and Prussian customs officers rubbed shoulders as they performed their duties. However, the Garnstock is also the place where the Religious Order of the Fathers of the Eucharist initially set up a convent. They were then followed by Franciscans who extended the building and, in 1934, built a church whose facing includes rough-hewn blocks of Baelen marble. Within the walls of the convent, a small cemetery still plays host to the modest graves of several monks who occupied the site until the 1970s/1980s. Today, the buildings belong to the Saint Francis of Assisi Foundation.
