Guard's cottage

In 1864, based on the designs by engineer Jean-François Radoult de La Fosse, two identical chalets were built on either side of the bridge in the style of the fabriques (small, fanciful structures) found in Paris parks of the same era. Parisian contractors Waaser and Madin, wood carving specialists, were commissioned to build them.
One chalet was reserved for the park ranger's quarters, the other for the administration.

Sometimes incorrectly referred to as the "chalet des suppliques", the surviving pavilion never actually handled the supplications addressed to the Emperor during his spa treatments in Vichy; a special mailbox was installed for this purpose, first at the Hôtel des Thermes (neighbouring the Villa Strauss where Napoleon III stayed), and then at the Town Hall. From 1885 to 1932 it housed Vichy's Octroi Tax Office (which collected taxes on goods entering the city, excluding basic necessities). The second chalet was destroyed during the widening of the bridge in 1935.
