La tour Bastian

Le Grand Piton is the highest point of Le Salève offering a view mainly focused on the Genevois region and Jura.
The tower was built between 1820 and 1830 by Claude-François Bastian, a wealthy notary and mayor of Frangy. Prior to the construction of this tower, this small plateau on the edge of the cliff, which features some of the Salève's finest lapiaz, was home to a 14th-century lookout post.
At the foot of the tower to the north-east, you can enjoy finding a cartouche engraved on the limestone with the names of Lord Byron and Lamartine.
