Château de Tallard, Medieval fortress in Tallard, France.

Château de Tallard is a medieval fortress built on a rocky outcrop with rooms, defensive walls, and fortified gates arranged across the site. The buildings connect through passages and make use of the sloping terrain to create different levels.

Tallard was under the protection of the princes of Orange from the 10th century until 1215, when they ceded the land to the Hospitallers, who built a small castle on the site. In 1322 it was exchanged to Arnaud de Trians, who began the fortress; in 1326 Tallard became a viscountcy with seven surrounding parishes. In 1692 the Duke of Savoy's troops burned the castle, which was abandoned until 1897.

The seigneurial chapel beside the entrance gate was built in the Flamboyant Gothic style after Bernardin de Clermont's 1496 marriage to Anne de Husson, heiress of Tonnerre, whose fortune paid for the castle's conversion into a residence. The same campaign added the long Salle des Gardes in the forecourt and the park of La Garenne.

Visits are usually possible during the warmer months when conditions for exploring the site are best. It helps to wear sturdy shoes since the paths are uneven and the ground is hilly.

The building was reconstructed after a devastating fire and later left to itself for decades before being restored in more recent times. This long gap means that parts from different eras sit side by side.
