Explore Isar through its distinctive architectural features: two churches display different Romanesque and Gothic characteristics; there is also the Torreón de Isar, preserved parts of a mill and the route to Monte de las Quintanillas. This makes the town a destination focused on local history and scenery for an overnight stay. It is particularly interesting if you want to consider architectural history as part of a wider picture, taking in various landmarks and a route when planning your trip.

Churches in Isar: Different Architectural Features

The Church of San Martín is a Gothic, single-nave church dating from the 13th century; two side chapels complete its layout. A single nave is a church space with one main nave; the chapels are set to the sides. Its Romanesque-Gothic portal, dating from the 13th century, has four pointed archivolts decorated with diamond-point motifs. The carved capitals depict acanthus leaves, human figures and fantastic creatures. The portal thus brings together a clear arch shape and figural decoration. San Martín also preserves a Romanesque crucifix from the 12th century.

Santa María is Romanesque-Gothic and has a rectangular nave, a choir with a Torceletes vault and a rectangular apse. It was built in the late 12th or early 13th century as a rural Romanesque church with a single nave, a choir with a flat end and a tower at the western end. Compared with San Martín, the focus here is more on the nave, choir, apse and the position of the tower, whereas the portal and side chapels distinguish the other church.

The Torreón and Milling Heritage

The Torreón de Isar has a rectangular ground plan. Its walls are almost two metres thick and up to four metres high; it is built of rubble masonry, with ashlar reinforcements at the corners. Rubble masonry is made of irregularly shaped stones; ashlar reinforcements use dressed stones at the corners. It is believed that the Manrique family built the palace-fortress associated with the Torreón de Isar.

At the Molino de Isar, a still-visible holding basin with its sluice gates and two arches have been preserved. Water flowed out through the arches after driving the mill machinery. Unlike the churches and the Torreón, the focus here is on the role of water in operating the mill.

Scenery, Route and Directions

The landscape is also part of Isar’s description, alongside its churches and the Torreón: the town lies in a valley watered by the River Hormazuela. The ISAR-MONTE DE LAS QUINTANILLAS route starts in Isar, leads to Monte de las Quintanillas and returns to Isar via El Castillete. You can treat the route as a separate activity alongside the architectural landmarks: both the starting point and the return point are in Isar. Check current trail conditions locally before setting out.

Isar is accessible via the Burgos–León motorway; take exit 145 near Villanueva de Argaño. Check road conditions before you travel.
