In the second half of the 19th century, the people and authorities of the Valais began to worry about the conservation of the Tourbillon Castle. With financial assistance from the State, restoration projects were launched; the idea of restoring Tourbillon to its medieval appearance was soon abandoned as it was considered too costly. The castle walls were consolidated, the tower to the south of the enclosure was rebuilt and the wall in the north-west corner was partially destroyed and then rebuilt identically. The work was completed in 1887, and Tourbillon became a favourite destination for tourists and the people of Sion.
