The Heritage Days, born in France in 1984 and now rolled out across around fifty countries, give the public each year the chance to discover sites that are normally closed or off-limits to most people. In 2026, they will take place on September 19 and 20, under the theme of “architectural heritage.” With renewed enthusiasm, heritage lovers are invited to uncover these little-known treasures, such as the Skit du Saint‑Esprit, which will exceptionally open its doors to the public for the occasion.
Perched in the Bois du Fay in Mesnil-Saint-Denis (Yvelines), the Skit du Saint‑Esprit is a small Orthodox monastery founded in 1938. This atypical complex actually comprises three adjoining churches, crowned by a green dome and blue onion domes, echoing Byzantine tradition. The interior is adorned with frescoes and icons by Père Grégoire Krug (1907‑1969), regarded as one of the greatest iconographers of the 20th century. These profoundly spiritual works are embedded directly into the walls using the traditional technique — an invitation to inward reflection between shadow and light. The site, still active, offers visits by appointment, notably during the Heritage Days.
Visiting the Skit du Saint‑Esprit during the Heritage Days is to step into an offbeat place, rich in striking architecture and a palpable sense of spirituality. Labeled as “20th‑century heritage,” this site offers a rare chance to admire icons signed by Père Grégoire in a setting that invites quiet reflection. The guided tours on Saturday, September 19, 2026, starting at 10:00, provide an exclusive glimpse of this exceptional site (registration with the Syndicat d’Initiative du Mesnil‑Saint‑Denis). For art and history enthusiasts—or anyone drawn to extraordinary places—this outing is a must: an immersion in Orthodoxy, a tour through a little‑known heritage, and a deeply inspiring experience, all set within a tranquil forest backdrop.
