The INN was built by the Duke of Lerma in the 17th century to entertain King Phillip III and his illustrious guests, including Rubens and Lope of Vega. It was adapted as a tourist accommodation in 2003.

The palace is built in staid Herrerian style, with well-balanced proportions and shapes. Its original exterior architecture is preserved intact. The main façade features a balcony and the coats of arms of the Lerma and Medinaceli families, evincing the building’s emblematic nature.

With 18 rooms, distributed over two floors, the INN also includes a dining room, a lounge, a coffee shop, a games room, a swimming pool, gardens, sports facilities (paddle court, tennis court, sports track, and hiking, running and bike routes) and a car park.
