Burgo de Osma: The outskirts
The city is situated within the so called Duero Route, which crosses
other Sorian towns. Almazán is distinguished for its historic
quarter, where the most outstanding features are the Plaza Mayor,
the three gates in the town walls and several churches. Berlanga
de Duero conserves the Castle of los Tovar (15th century), a bastion
which still retains two walls and a keep, and the collegiate church
of Nuestra Señora del Mercado, in Gothic-Renaissance style.
Following the flow of the Duero appears San Esteban de Gormaz and Ucero, at the top of which are the walls of its medieval castle. The route cannot end without visiting Calatañazor, where the Romanesque church of Nuestra Señora del Castillo and the walls built between the 12th-13th centuries can be seen.
The outskirts of El Burgo de Osma allow you to discover surroundings with a high ecological value. The Canyon of the River Lobos, declared a Natural Park, has numerous caves and rocky cliffs where eagles and crested vultures nest. In the interior of this park you can also find the Romanesque hermitage of San Bartolomé, of Templar origin.
