The carousel wheels are made of wood and must roll in a water-filled track to minimize wood shrinkage and prevent irreparable damage.

Each quadrant of the platform features a gondola preceded by two groups of three horses, for a total of four gondolas and 24 horses. The carousel was named Le Galopant because of the galloping motion of the horses and gondolas, which are controlled by an ingenious mechanism.

The first gondola is unique, representing a winged angel holding reins. The second possesses a canopy supported by nymphs in profile. The third features a figurehead of a woman holding a torch. The fourth gondola has a canopy that sits atop posts decorated with arabesques.

The wooden horses are made of a number of parts precisely assembled with wooden pegs and rabbit glue.

All the decorative elements were produced in Belgium by a sculptor named Jules Moulinas.

The organ, designed to be a miniature orchestra, is mounted on its original carriage. Formerly, the engine supplied the power required to run a leather bellows, which in turn operated its own mechanism, various instruments, and wooden flutes.

This organ read music from perforated paperboard sheets connected end-to-end with a special adhesive. One song required 48 sheets.

The Galopant organ is worthy of being called an orchestrion—the name sometimes given to this type of musical instrument—because its 89 touch keys, which activated 327 flutes, two drums, one cymbal, and two clappers, produced an orchestra-like sound.

Today, the music played is the same as that on the perforated paperboard sheets used in 1967. It is, however, recorded, because the organ was not restored due to the immense complexity of this task.
