Reials Col·legis de Tortosa, Renaissance monument complex in Tortosa, Spain.

The Reials Col·legis de Tortosa is a Renaissance complex of three buildings: the College of Sant Jaume i Sant Maties, with a two-storey rectangular courtyard on three levels (the lower two with round arches, the upper with segmental arches) and a carved frieze of 19 royal couples from Ramon Berenguer IV and Petronella to Philip III and Margaret of Austria; the College of Sant Jordi i Sant Domènec, of which only the two-body doorway with the inscription DOMUS SAPIENTIAE remains; and the Church of Sant Domènec, a single nave with side chapels and a three-body doorway.

Construction began in 1564, when the colleges were established to educate young Muslim converts in 16th century Catalonia. Over time the institutions transformed into general educational facilities serving the broader local population.

The courtyards feature sculptural elements displaying busts and coats of arms from the royal dynasties of Aragon. These decorative choices show how education and royal authority were intertwined in the minds of those who built these spaces.

The three buildings stand within Tortosa's historic centre: the College of Sant Jaume i Sant Maties houses the Baix Ebre Regional Archive, the College of Sant Jordi i Sant Domènec serves as the Education Department's territorial offices and the Official Language School, and the Church of Sant Domènec is the city's ceremonial hall and hosts the Renaissance Interpretation Centre. The courtyard of Sant Jaume is the main element to see; its arcades and sculpted frieze are best examined up close.

The courtyard of Sant Jaume i Sant Maties features a rare Renaissance loggia in Catalonia that blends religious and scientific imagery in its decoration. This combination reflects the intellectual environment that shaped the colleges at their founding.
