The shore here provides a haven for swans as well as small ferries which ply the harbor, while at the end of the jetty, a small metal column acts, miraculously, as the Jet d'Eau source. Spewed by electric pumps, the weight of the water as it shoots in the air is a full seven tons. From the week of Ascension Thursday in May until the first Sunday of October, the Jet d'Eau is illuminated at night.
