Casa de los Jaenes

Casa de los Jaenes is an 18th-century townhouse standing on Plaza de la Constitución in La Guardia, a small town in the province of Toledo, in the Castilla-La Mancha region. Also known as Casa de la Inquisición, the building now houses an ethnological museum dedicated to the traditions and daily life of this corner of Toledo.

Where is it and how do you recognize it?

The house sits right in the heart of La Guardia, at number 3 Plaza de la Constitución — a square that until recently was called Plaza de los Mártires. It's a central spot within the old town, surrounded by other historic townhouses that make up the traditional layout of the settlement. The building's most distinctive feature is its Baroque stone facade, well preserved and still showing Mannerist touches from an earlier architectural period. The facade carries the Jaenes family's heraldic shield, along with two dates — 1736 and 1754 — marking stages of construction and later remodeling.

Who built it, and why?

The house was commissioned by Sebastián de Huerta, secretary general of the Inquisition and a native of La Guardia — which explains the building's alternative name, Casa de la Inquisición. The coat of arms on the facade, however, refers to the Jaenes family, whose members were named Knights of the Golden Spur by Emperor Charles V. This mix of two different traditions — one tied to the Inquisition, the other to nobility — makes the house's backstory unusual compared to other historic residences in the region.

What can you see inside?

Today the building functions as the Ethnological Museum of La Guardia, displaying objects and testimonies connected to local customs, crafts and everyday life across generations of townspeople. The interior architecture, though adapted for museum use, still carries traces of its original role as the residence of a well-off bourgeois family.

Is it a protected heritage site?

Yes. Casa de los Jaenes was declared a Bien de Interés Cultural — a Cultural Heritage Site of local significance — in 1991, confirming its historical and architectural value within the heritage of Castilla-La Mancha. That status protects the building from alteration or demolition and requires proper conservation of its facade and surviving period features.

Why visit La Guardia?

La Guardia is one of those smaller towns in the province of Toledo where history shows up at every turn — in the street layout, the stone facades, the central squares. Casa de los Jaenes makes a natural starting point for exploring the rest of the old town, and a stop at its ethnological museum helps put the region's culture in context before moving on — whether that's to Toledo's better-known sights nearby or to the vineyards this part of Castilla-La Mancha is known for.
