Listed as a historic monument, the Tour d’Avalon is an integral part of the Grésivaudan valley’s historical heritage. It was built by the Carthusian monks on a former keep. In the 1000s, the lords of the Wallon-Romestang d’Avalon family had a feudal castle here. The Tour d’Avalon, built on these ruins, is constructed of limestone rubble and ashlar. Flanked by a neo-Byzantine chapel, it boasts 3 levels and a machicolated terrace. The interior diameter is 8 metres.

Old stone enthusiasts will be able to admire part of the 14th-century walls that still bear witness to the castle’s status as a stronghold. The tower was also a symbol of power for the castle’s masters.

“A very well-preserved monument full of history”.
