João de Castilho

João de Castilho (c. 1470–c. 1552), also known as Juan de Castillo was a Castilian and a notable Iberian architect born in Castillo Siete Villas, actually Arnuero (Cantabria). He is recognisably one of the premier architects in Portuguese history (where he developed most of his work), responsible for several World Heritage buildings. He was a Spanish-Portuguese master builder and architect originally from Cantabria (former Kingdom of Castile; present-day Spain), who developed his mature career in Portugal, where he settled in c.1508. He is considered the greatest Iberian architect of the 16th century and one of the greatest in Renaissance Europe.

Trained in the gothic style, his activity made its mark during the Manueline period, after which he played a decisive role in affirming the Renaissance style in Portugal. João de Castilho was one of the major protagonists of a decided shift towards classicism. His career also highlights the gradual promotion of the position of master mason (medieval) to that of architect – in the modern sense of the word – with the corresponding recognition and rise in social status.

Author of a vast and notable body of built work, João de Castilho is linked to the building of five historic monuments classified by UNESCO as World Heritage, two great highlights being the Jerónimos Monastery and the Convent of Christ. Among many other works for which he was responsible, he also contributed to the Alcobaça Monastery, the Batalha Monastery and the Mazagão Fortress (El Jadida), also classified as World Heritage.

In 2022, Indonesian composer & pianist Ananda Sukarlan composed "Castillo Reconstruido" to commemorate his 550th anniversary, commissioned by the Arnuero International Chamber Music Competition in Spain. The 10-minute piece is for piano, accordion, cello and clarinet.
