Raul Lino da Silva, better known as Raul Lino (Lisbon, 21 November 1879 - 13 July 1974) was a Portuguese architect, designer, architectural theorist, and writer.
Lino's architectural theses and studies revolved around the theory of the Casa Portuguesa (Portuguese: Portuguese house), an idealized concept of Portuguese residential architecture, planning, and lifestyle.
The cities of Cascais and Sintra, along the Portuguese Riviera, boast the largest concentration of Lino's constructions out of anywhere.
Lino played an active part in the cosmopolitanization of Cascais as a summer resort for the wealthy and notable and in the continuation of Sintra as a historicist, romanticist haven.
