The Lede Formation (Dutch: Formatie van Lede; abbreviation: Ld) is a geologic formation in the subsurface of Belgium. The formation is named after Lede. It consists of shallow-marine limestone and sandstone, deposited in the former sea that covered Belgium during the Eocene. The bluestone (for roads) and in particular the yellow-brown calcareous sandstone extracted from quarries in Lede and neighbouring areas, were widely used during the 15th to 18th century as construction material for religious and civil buildings.
Lede is known for a statue of the Virgin Mary, called "Onze-Lieve-Vrouw-van-Zeven-Smarten" (Our Lady of the Seven Sorrows), to which a local legend attributes magical powers. The statue attracts many pilgrims. The statue is taken around in a procession during a Sunday in June, after the biannual nine-day festival. The local church, built in 1496, houses the statue.
The abandoned Mesen Castle is situated in central Lede. It used to be the residence of the Marquess of Lede. Its demolition was started in April 2010.
