In the cradle of Portugal, the Historic Centre of Guimarães hides a perilous guild secret from the 12th century
You are a royal archivist in 12th-century Guimarães, mandated by Afonso Henriques to record the kingdom's foundations.
Your mission leads you to Guimarães, a UNESCO-
Dive into the heart of Guimarães, the Cradle of the Nation, where ancient stones whisper the epic tale of Portugal's birth.
« Portugal Was Born Here »— Motto of the city of Guimarães
Your quest begins at the Tour da Alfândega, or Porta da Vila, a fortified entrance gate from the 13th century, classified as a National Monument in 1933. Standing 15 meters high, with its ogival arch and defensive machicolations, it was restored in 1940 for Afonso Henriques' 800th anniversary. It is here, at the entrance to Guimarães's historic center, that the city's first builders erected their landmarks. You decipher the carved symbols that once guided artisans and merchants entering the medieval city, the heart of Porto-et-Nord's heritage.
Continue towards Praça de São Tiago, the main square paved with local granite since the 14th century. This 2,000 m² site, surrounded by noble houses from the 15th-16th centuries, was the scene of Portugal's independence proclamation in 1128 by Afonso Henriques. It was on these cobblestones that the Festas da Cidade took place, and where medieval guilds gathered. Your register reveals the names of the master builders who shaped the urban identity of Guimarães, the Cidade das 7 Colinas.
The path then leads you to Rua de Santa Maria, one of Guimarães's oldest streets. This 12th-century paved road, 300 meters long, is lined with 18 stately homes from the 14th-18th centuries, some with Gothic arcades. In 1838, this street hosted the first public theatrical performance in Portugal outside Lisbon. Here, you discover clues about the city's architectural evolution, from Romanesque foundations to Baroque embellishments, a testament to Guimarães's rich heritage.
Your exploration of the Builders' Register takes you to the Paço dos Duques de Bragança. This flamboyant Gothic palace, built between 1401 and 1425 by Dom Afonso, illegitimate son of King John I, served as the residence for the Dukes of Bragança until the 17th century. With its 3,500 m² of red tiles and 52 decorative chimneys 10 meters high, this National Monument, classified in 1907, is a masterpiece. Here, you piece together fragments of a dynastic history, revealing how stone and power shaped Portugal's identity, the Berço da Nação.
Your journey concludes at Largo do Toural, a rectangular square of 4,000 m² paved in 1772, formerly a medieval fairground. The equestrian statue of Afonso Henriques, erected in 1895 by António Teixeira Lopes, dominates this space where bullfights took place until the 19th century. Here, the Builders' Register is completed, offering you a finished vision of the ingenuity and perseverance that built Guimarães and, by extension, Portugal. This circuit has immersed you in the history of Guimarães, leaving you with a deep understanding of the monuments and legends of Porto-et-Nord.
