Lisbourg offers three specific points of interest for planning a trip: the bas-reliefs at the west portal of Église Saint-Omer, the blue springs of the Lys and the Haute vallée de la Lys hiking route. This makes it possible to tailor your stay to different interests—sculpture and heritage, the source of the river, or a hike with a stated distance. If you are looking for a hotel in Lisbourg, it helps to decide first which of these focuses matters for your stay.

Reliefs and defensive heritage

Two bas-reliefs are located on the exterior of the west portal of Église Saint-Omer de Lisbourg. They depict the Virgin Mary and, probably, Saint Omer as a bishop; the identification of the second figure is therefore uncertain. Since 11 May 1984, both reliefs have been protected as movable cultural property. Here, sacred sculpture can be viewed through a specific pair of subjects, without overlooking the uncertain interpretation of the second relief. The exact date of protection and the classification as movable cultural property give the reliefs a distinct cultural and historical significance.

Another cultural point of interest is the Motte féodale de Lisbourg, which is part of the defensive heritage. The two subjects offer different emphases: the reliefs feature figurative imagery, while the motte is classified as defensive heritage. This distinction helps orient visitors between sacred sculpture and defensive heritage, rather than reducing Lisbourg’s history to a single theme.

Source of the Lys and hiking route

The Lys rises in Lisbourg; its blue springs can be discovered from the road between Lisbourg and Laires. The connection between the river’s source and the view of the springs gives the nature theme a specific point of reference. The site providing access to the source for visitors was inaugurated in June 2007. This date places the development in context and provides a historical reference point if you are interested in the history of the source site.

The Haute vallée de la Lys is a 21.80-kilometre hiking route that starts and ends at Place de Lisbourg. It passes close to the source of the Lys. The distance and the shared start and end point make it easy to consider the route as a standalone hiking option. A note from mid-April 2026 mentions a potentially usable picnic spot near the source. Treat this spot as a possibility, not a given. Trail conditions may vary; check them before setting out.

When choosing between seeing the source and going for a hike, the difference is practical: the springs can be discovered from the road between Lisbourg and Laires, while the 21.80 km route passes close to them and begins and ends at Place de Lisbourg. This gives you two clearly distinct ways to explore.
