Torre Loizaga (Castillo Concejuelo)

Castillo Concejuelo is located in Concejuelo de Galdames, Spain.

The building at the site is a tower house whose historic fabric was later renovated and adapted for contemporary use. The record identifies the structure as a restored tower house but does not assign a specific construction date or original builders.

In its most recent phase the complex was transformed to serve as an automobile museum. The museum is especially noted for its Rolls‑Royce holdings: forty‑five Rolls‑Royce cars are exhibited within three purpose‑built pavilions, and seventy‑five vehicles are on display across the site. Among the collection are an 1899 Allen Runabout and a 1956 Rolls‑Royce Phantom IV that once belonged to HH Abdullah III Al‑Salim Al‑Sabah, Hakim of Kuwait.

The site operates on a summer schedule from 10:00 to 15:00, with an admission charge of €7 for adults and €3 for children aged 12 to 18. Access is often arranged by an authorised tour bus; the site is described as difficult to find by some visitors and is situated about a 45‑minute drive from Bilbao. Driving directions recorded for reaching the property include exiting the A‑8 at Abanto y Ciérvana‑Abanto Zierbena, following the N‑634 toward Somorrostro Muskiz, taking the BI‑2701 to Sopuerta, then the BI‑3631 east toward Galdames Güeñes to kilometre marker 33 and finally a mud track leading south marked toward Torre Loizaga.
