Croix des Fiancés, Memorial monument near Baraque Michel, Belgium.

The Croix des Fiancés stands on the High Fens plateau near Baraque Michel, on the old fagnard track called La Vêquée and the former Belgium-Prussia border. It consists of a tall, narrow grey stone pillar with worn lettering near its top, beside a dark wooden cross on a pale stone base with a small central plaque.

A first cross stood on this spot from at least 1906. The present memorial was inaugurated on Sunday 20 September 1931, on the old fagnard track La Vêquée and the former Belgium–Prussia border, in memory of François Reiff and Marie Solheid, lost in a snowstorm on 22 January 1871.

The cross stands on the old fagnard path La Vêquée, on the former border between Belgium and Prussia. It replaced an earlier cross present on the site since at least 1906. The 1871 drama inspired Stéphane Xhroüet's film Deux enfants du siècle (Wil & Wâtie), released in early 2021, with Marie Gillain and Ulrich Tukur.

The monument sits along marked hiking trails in the Hautes Fagnes Nature Reserve, accessible from parking near Baraque Michel. The exposed moorland terrain can be windy and wet, so sturdy footwear and appropriate clothing for changing weather are recommended.

Marie Solheid's body was found two months after the storm, in spring, by a Prussian customs officer, about 1,500 metres from the Baraque Michel inn. In her bodice lay a note in her fiancé's hand: "Marie vient de mourir, et moi, je vais le faire." François Reiff's body had already been found two kilometres away, on the heights of Solwaster.
