Tilleul de Pérouges, Classified natural site linden tree in Pérouges, Ain, France

The Tilleul de Pérouges is a linden tree standing on the cobbled Place de la Halle in the medieval town of Pérouges. Its thick, deeply furrowed trunk flares at the base and is hollow inside; a tall wooden pole with two diagonal braces supports it. The broad, rounded canopy shows green leaves with some yellowing.

The linden was planted on 21 April 1792 in the centre of the Place de la Halle, in the medieval town of Pérouges in the Ain. It is a classified natural site, pruned and maintained by the Office national des forêts. Its trunk is now hollow and the tree is slowly dying, held up by heavy wooden pillars.

The tree stands on Place de la Halle, also called Place du Tilleul after it, in the medieval town of Pérouges. Planted on 21 April 1792, it is a site naturel classé, and the Office national des forêts prunes and tends it. Its hollow trunk is held up by heavy wooden pillars.

The tree is freely accessible on the village's central square and can be visited at any time. Visitors should note that the tree is under constant care, and the wooden structures around it help maintain its stability.

The trunk has transformed into a tubular structure after hundreds of years, appearing green and alive from the outside despite being completely hollow inside. This unusual structure allows the tree to continue growing despite its advanced age and the absence of wood on the inside.
