Muntsaratz Dorretxea (Abadiño)

Abadiño-Zelaieta, Spain, Spain

---

Muntsaratz Dorretxea is a Renaissance-style tower-palace in the Muntsaratz neighborhood of Abadiño, Bizkaia province, Basque Country, Spain, originally built as a defensive fortress in the 9th century and substantially remodeled in the 15th-16th centuries.

This rectangular stone structure on the Zumelegui River's left bank features five floors—stables below, kitchen and bedrooms midway, residences above, and a Tuscan-columned gallery at the top for storage—plus family coats of arms and thick sandstone walls reflecting its evolution from stronghold to noble residence.

Home to powerful lineages like the Muntsaratz, Guisasas, Allendes, and Azkarates until 1977, it was restored in the 1980s-1990s by local authorities and now serves as Hazi Foundation headquarters, showcasing Bizkaia's finest civil Renaissance architecture.
