On Monday 9 November 2026, POST Luxembourg announced the opening of its Kleeschen (St Nicholas) Secretariat for those all-important festive letters.
POST Luxembourg emphasised that it has been “a loyal partner of Saint Nicholas” since its foundation in 1842 and is once again opening the Kleeschen Secretariat as the end-of-year celebrations approach.
The local postal service will forward the letters to St Nicholas but, before doing so, will send a reply accompanied by a small, playful surprise to each sender. It is therefore essential to indicate the sender's address correctly to receive a reply.
In 2025, more than 8,900 reply letters were prepared by the Kleeschen Secretariat at POST Luxembourg, where employees ensure that even letters with a slightly incorrect recipient address reach their destination. Members of the POST Luxembourg staff association (Amicale) also help prepare the replies.
Letters addressed to Kleeschen can be dropped off, postage-free, in all POST yellow letterboxes throughout the country. In addition, POST provides a printed greeting letter template through its retail network. The template is also available to download at www.post4kids.lu.
The postal address for letters to Kleeschen is: Kleeschen (1 Spillstrooss, L-3290 Am Himmelsland)
Meanwhile, Home from Home in Strassen will once again offer a Santa postbox for children wishing to send their festive letters. The postbox will be open from Tuesday 1 December until Christmas. Its postal address is: Home from Home (148 Route d'Arlon, L-8010 Strassen).
