The municipality of L’Estany forms part of the rural county of El Moianès and it sits on a plateau that rises from 600 to 900 m above sea level. The population is just over 400 and the municipality covers an area of 10.2 km2.
The relief of the land within the limits of the municipality is the result of a series of geological folds, faults and overlaps that were formed over 25 million years ago. It is a natural basin surrounded by peaks, ridges, hills and passes that together encourage water to easily accumulate at the bottom of the depression, which is nowadays occupied by the meadow located to the south of the village. Less than 11,500 years ago the water that collected there created a lake which, despite the fact that it no longer exists, still lends the village its name.
