Château Delphinal

Château Delphinal is a medieval fortress perched on Saint-Laurent hill, featuring a round tower with crenellated walls and a chapel carved directly into the rock. The west-facing side was redesigned in the 1900s, while the carved architectural details remain visible throughout the structure.

First documented in 1222, this fortress served as an administrative center at the edge of the Dauphiné region before the lords of La Tour rebuilt it starting in 1282. The chapel underwent restoration in 1633, and later the structure was partially dismantled for stone by inhabitants.

The chapel integrated into the castle shows how medieval builders worked with the natural rock face to create their spaces. The carved stone window from the 1200s reveals the craftsmanship people valued in religious settings.

The site sits on a steep hill reached via Montée Saint-Laurent street in the town center. Visitors should check opening hours and access conditions in advance since the location has varied terrain and may have seasonal limitations.

The ruins were used as a stone quarry in the 1600s by the Visitandines, a practice that affected the shape of what remains today. Walking through the site shows where material was extracted from the walls.
