Mata Castle Museum

Las Palmas de Gran Canaria, Spain, Spain

---

Mata Castle Museum, or Castillo de Mata, in Las Palmas de Gran Canaria, Canary Islands, Spain, is a 16th-century fortress built around 1572 by engineer Juan Alonso Rubián as part of the city's defenses against pirate attacks, notably repelling assaults by Dutch admiral Pieter van der Does in 1599.

Located in the Triana district near the Cabildo Insular building and originally a round tower along the old walls, it was reconstructed after damage, served as barracks until the 20th century, and was declared a Historic-Artistic Monument in 1949.

Recently restored and opened as the City and Sea History Museum, it features four exhibition halls and a vault displaying Gran Canaria's fortifications, archaeology, and maritime conflicts through interactive exhibits amid its historic casemate structure.
