Diogo de Arruda

[1][2] Between 1508 and 1510, he was the architect of the Paço da Ribeira bastion erected by Manuel I of Portugal in Lisbon, in an area on the right bank of the Tagus River.

[3] Diogo de Arruda was one of the great names associated with the Manueline remodelling of the Convent of Christ, serving as a master there from 1510 to 1513.

[6][7] The entire west facade of the choir, flanked by two large buttresses, is abundantly decorated with heraldic and naturalistic motifs.

The design of this castle, with a square plan with turrets at the vertices, follows Renaissance models of military architecture and represents an innovation in the country.

[14] At that time, he likely participated in the works of the Paços Reais de Évora, a large palace complex that had been under construction since the 15th century.
