Castles and fortified palaces

Guimarães Castle originated in a tenth-century foundation associated with Countess Mumadona Dias and the protection of a monastery. Much of the surviving stone castle, however, belongs to later medieval construction. Granite walls enclose a compact courtyard on the hilltop, with towers and restricted entrances providing successive defensive obstacles. Its present fabric should therefore be understood through those later building phases as well as its early foundation.

Evoramonte Castle has a different form: a compact, sixteenth-century fortified palace with four rounded corner towers. Horizontal bands divide its storeys, and carved stone ropes with knots encircle the building. The broad towers and roof platform accommodated artillery, while the enclosed block also served residential purposes. Its rounded mass and decorative bands distinguish it from the wall-and-courtyard arrangement at Guimarães.

Roman towns and houses

Conímbriga preserves an extensive excavated settlement with streets, baths and substantial houses. Residential buildings were organised around courtyards, including the House of the Water Jets and the large House of Cantaber. Mosaic floors retain geometric patterns, plants and figurative scenes, while heating systems and private baths show how some households equipped their rooms. These surviving surfaces and room arrangements make domestic buildings a central part of the site.

Ancient temples

The Roman Temple of Évora provides a standing example of the city’s public religious architecture. Its raised podium, fluted Corinthian columns and entablature preserve much of the temple’s exterior structure. It belonged to the Roman forum and is generally associated with the imperial cult. The familiar identification as a temple of Diana is not supported by the later archaeological interpretation.

Aqueducts and water supply

The Évora Aqueduct, also known as Água da Prata, was begun in the 1530s under John III. Its water supply followed a route of about eighteen kilometres, using conduits and granite arcades to carry water towards the city. It is a sixteenth-century engineering work, despite its setting among Évora’s Roman remains.

Within the city, houses and plots were fitted into spaces beneath the arches. These infilled sections give the aqueduct a close relationship with ordinary streets and buildings. Elsewhere, exposed arcades make the repeated arches and their supporting piers easier to follow as a continuous water-carrying structure.

Monasteries and palace complexes

Batalha Monastery was founded by John I after the Battle of Aljubarrota in 1385 and developed as a Dominican monastery and royal burial place. Its Gothic church rises beneath stone vaults, with flying buttresses supporting the exterior. The Founder’s Chapel and the later Unfinished Chapels added distinct dynastic burial spaces. A richly carved Manueline portal marks the latter complex, whose construction continued through several reigns without completion.

Mafra Palace combines a royal palace, convent and basilica in a vast eighteenth-century composition commissioned by John V. The basilica occupies the centre of the long façade, with royal residential areas to either side and the convent extending behind. Inside the library, wooden bookcases rise in two levels above a floor of pink, grey and white marble. Its arrangement brings royal accommodation, religious buildings and a major library into a single planned complex.
