Situated in the north-west of the province of Burgos in a region of dramatic landscapes shaped by a succession of mountains, ravines formed by powerful rivers such as the Ebro and Rudrón, and Las Loras, spectacular rocky uplands.
The town is surrounded by steep slopes and rocky formations. The first settlers date back to ancient times, as evidenced by the many dolmens and funerary megaliths that have been discovered in the area. More than thirty funerary monuments have been discovered in La Lora, although five have been reconstructed. Sedano has a visitor centre providing full details of these discoveries.
