The San Martín tower was built in the 17th century by Juan Antonio Díaz Trechuelo García de la Yedra, Grand Inquisitor of the Spanish Inquisition Tribunal in Logroño.
The property is located in Quintana de Valdivielso, in the province of Burgos, within the culturally and ecologically rich region of Castilla y León. The Valdivielso Valley is known for its medieval castles, towers and Romanesque churches — offering both scenic beauty and solitude. Surrounded by the Tesla and Tudanca mountain ranges and crossed by the Ebro River, parts of the valley are designated Special Protection Areas for Birds (ZEPA). The region also allows hunting (wild boar, deer, roe deer) and fishing.

- Top floor approx. 690 sq ft (64 m²)
- Floors 1–3 each include a balcony

A tranquil inner courtyard of approx. 1,290 sq ft (120 m²) includes original stone basins and a decorative cast-iron fountain.
Additionally, the property includes 1,615 sq ft (150 m²) of land with planning permission for future construction.
