The Franzosenweiher is located in a depression between the northern slope of the Heitersberg and the Sandbühl hill, in the forest between Spreitenbach and Dietikon. The pond was originally created by monks from the Wettingen monastery for trout farming. This is where the original name "Chlosterweiher" comes from, which can still be found on old maps today. In 1799, Napoleon's troops set up camp in the Baden region and also in Spreitenbach. The French supposedly emptied the pond before they left in order to steal the fish. This gave rise to the local name Franzosenweiher. Today the pond is a nature reserve and an ecologically valuable habitat for amphibians.

Legend of Egelsee: Among the knights who once lived in our land there were many godless and violent people. No traveler on the road, no seed in the field, no ox at the plow and no carving in the trough were safe from them. They robbed, burned and murdered whatever fell into their hands. Such a monster of a knight also lived in a castle on the Heitersberg. His name was Riko. But his castle was called Bauernweh because it only brought misery and misfortune to the farmers in the area. For the knight went out every day with wild dogs and rough companions in arms and returned to his castle in the evening with heavy robbery. On the way back from one such foray, they once came to the farm of a widow who had not been able to pay the interest on time. The monsters packed up the woman's belongings, drove her and her children out of the house and set it on fire. The mother only wanted to take a handful of flour with her to make porridge for her youngest child. Then the knight tore the child from her arms and threw it into the flames. "Now there's no need for porridge anymore," he sneered and ran off with his flock. The mother knelt in agony by the burning house and begged heaven to have mercy on the people and end their misery. And heaven heard the lamentation of the unhappy mother. That same night a terrible storm hit the area. Lightning flashed down on the castle without interruption, and with a mighty crash it sank, along with all hands, a hundred fathoms deep into the abyss. The following morning a deep, black lake lay where she had sunk. For a long time he was feared and avoided by people. It's the Egelsee
